Answers

Determine the force in each member of the truss and state if the members are in tension or compression. Set $P_{1}=8 \mathrm{kN}, P_{2}=12 \mathrm{kN}$

We'll be looking at structural analysis. Consider the structure where we need to determine the forces, the market forces in the members as well as their nature. Okay now for this problem we will apply the middle of joint soviet. And the community places place to start from this joint D. So I joined the we have a force coming like this. Yeah obviously uh horizontal force. Okay so three D. C. G. Force going to uh Remember this is 20 to see uh the Anglia is 63 314°. Use your the information given the question is fine to figure it out. Okay this is a force have this top secret E. Okay and this is a joint D. That we are considering? Okay join us deep. Yeah. Okay and that is this uh illuminating force given any question? Okay. I joined D. Now take submission of forces in the horizontal direction. Mhm. People to zero. They're going to arrive at -F. So sweet D. C. Mad as F. She was with E. Okay that force costs just three points 0.4 degrees Equal to zero. Can call this equation one uh Take assumption of forces in the vertical direction. Also arrive at my last date was uh So it's three d. E. Mhm. Sign three three 14 degrees you quarter zero. I'll call this equation too soft music question with some from question too young to arrive at. Okay social media is equal to 89589 50 muting. Okay the new team. You can see that this member is on the attention because it's positive. Okay considered to plug this value into question one and you arrive at that's the street tough. The D. C. We equal to minus for killing muting retail. So that the forces the force on the story. Remember. So that compression. Yeah. Why remember E. Come with me First value. God. uh 8.95 agreements on that tension. The members of the attention. These members on the compression. Okay. You can also look at a joint seed. So what did you see if you look at that point we have something that looks like this. Uh The forces should be going out of the joint. Okay. That we're considering he joined on that consideration. So happy is for sea going to e. from joint c. two e. Without this long. Okay. To be happy. So All right, can take submission of forces in the horizontal direction to do that you're going to have on this C. B. Mm. Yeah. Have such received C. B. Lost. Elf Social cd three quarters zero. So that also receiving okay, supposed to have social cD copies. And of course we already know the value of the city. So that means this one is gonna give us just plugging up here for kilo newton far this negative for muting. Yeah. So this force is a member under the member is under compression. Yeah mm. See Because of the negative sign. 15. Now, if you look at from inspection. The force see uh F. E. Zero. Okay because that's foresee this fourth year the member is joining is coming out from a joint. Okay. Is it between two colonial forces? Okay. And there's no standard for the Russian community person to remember. So zero. So you can just say F. Source received C. E. What? Zero? Mhm. Yeah. Okay they will come. That one is equal to zero. You can look at other. I look at that point. Yeah So this one is 0. No so you can look at other joints. Let's consider joints. Joint E. Look at you and E. Have this force coming like this some common streets so the forces will coming out of the joint. Yeah. Is a joint E. Yeah this is fc receive E. Do are you going to be joint E. Going to Mhm. See and you're from E. Yeah. Going to be Mhm. Yeah. Yeah. Okay. Now this angle we can figure them out using the information given in the Diagram these 45°. This is 45 degrees. Okay This is 26 0.6 degrees. And if you take this on the angle you're going to give you 64 3 14 degrees. Mhm. Good. Yeah fine. So let's check the other ones you need. Yes it was that angle is three point so you can take solution of forces in the oh vertical direction. Study vertical direction. Okay we're going to have this one so that we have to remind us F. So sweet E. Yeah E. B. Course. Right. Also at 5:45° maybe something. Mhm. Mhm. Good. My last F. South street E. G. Okay. Uh cause 26 26 0.6 degrees quarter zero. Now to solve this, we're going to have that starts with E. A. B. To the equal to Mhm. I don't have this force. Maybe to be equal to mine level plugging all the values I need to plugged in. Mm Yeah 32. Okay. Kill annuity. Is it interesting? Three new team. This member is on the compression because you can see compressive force because of the negative. Okay. We can also consider uh continue with john look assumption of forces in the horizontal direction. Okay. We looked at the vertical direction direction on zero. You're welcome. Do I want to have uh Yeah minus actual street job? Mm E. B. Yeah. Mhm. Sign. Mhm. Okay. 45 degrees. Mhm mm. Loss. Have social E. G. I want to look at me signed 26. What is going on? Mhm. My 60 degree mellows F. So ST E. F. Mhm. Equal to zero. We saw this are able to arrive at plug invalid. I've gotten already Panorama. S source with E. F. Making it is sort of the formula to be equal to mhm mm At one point five kids. I feel a new team. Yeah, I can't see it. I just remember it. It's on the attention. Anything. Okay. Now we can also look at joint john b look at your auntie. We also have a Yeah. Within being Yeah. Have this force. Yeah. Like dicks up is a joint B mm From the information given in the ground. The structure figure all the angles. Yeah. Okay. Go into that direction. This is 45°. Just get you can get it from the from the information given in the diagram structure. Your question. Okay. These forces have be going to be going to have okay on this piece. Its forces. You can coming out of the joint assumption. Yeah. Is everything? Yeah. And this is F. B C. Mhm. Okay. We're going to see these are thank you. And you think given any question, the check out You want that she was a 10 kN. I can be, yeah. Mhm. So when you stop this one takes a mission of forces in the yeah, vertical direction I'm going to have uh mm. I understand. Mm. Yeah. Yeah. Lost soft drinks. BF. Yeah. Yeah. Boy. Okay. It was after. Yeah suffered. B. E. Okay. Yeah, Signed 45°. Yeah 60. So when you saw this other and a half baths or strings, we have taken this into the formula. Of course. You know Elsa be already logged in the value there. The half 17 points seven decades. Mhm. Little new T. V. Mhm. I can see that. Remember the under pension. Yeah. Yeah. Then we can look at this for the yeah. Mhm. What? I was looking at the presumed to direction. Mhm. Okay. Security forces in the result of direction. Mhm. Bill dots with dots. Can have my nose. Look at the diagram. Yeah. I've drawn for the joint copies. Los F. Scott with Bc. Yeah B. C. Plus F. So streets B. E. Costs 45°. Mhm. Okay. 45 some quarters zero. Mhm. She plugging all the values in and like absolutely be a result of the Formula Man four is going to remember b. A. A Little Harvey to B -12. Mhm. Kill a new team. Mm Very different. Mhm. Cool. You can see that this member is under is under compression. It's under compression. You can just put it on us. Let's put it violent. There is actually equal to 12. My the mandatory is to have you know a new team. Mhm. Mhm. Okay. Mhm. That's you on the compression. Okay then we can we can look at a joint F. To consider doing F. Mhm. I have a lot of these uh something that looks like this. This is a joint. Okay. Okay we have this force coming down this is F. Mhm. Soft streets. So let us try to work. Yeah. Yeah strips. Okay. He's also street E. V. Yeah our joints considering F. Okay. Mhm. Yeah that would be I'm not happy because you cannot do an F. Okay. Going to be happen to me then we have during F force have to mm. Mhm. Sweet and a community forces should be going out of the joint and this one is doing f. Sorry for Steph something MG. Good friend. Yeah. After G. And this is F. That people. Okay so this angle is okay 3.4°. So you can use the information given in the question to figure out on this angle. Okay then when you take submission of forces in the horizontal direction, that little Alright house minus F. South Street F. E. Got some of the community or glows F. Mm. That's the streets. F. E. Sorry this one is absolutely f.g. Okay. Ss with F. G. This is F. G. Jim. This is S A. F. E. Your final stuff you through south streets. FDA. You have not the war. Yeah. Mhm. Sign 26.6°. Yeah. 26.6. The report to zero. So many forces. So when we do that we'll service at antique sumption of forces. Okay. In the vertical direction. If we look at sumption of forces, vertical Russian. I think that people will go away. I swear they're going to have miners. He's in a dark room. Have social F. Yeah correct. Mhm. Mhm. E. Mhm. Yeah. Mhm. Uh huh. Cause mhm 6.6. Mhm six degree. Mhm. Okay minus. Mhm. That's something also sweets. That's B. It was zero mm. So last night is always 26. 20 six. 26.6. Okay. And 6.6°. So I'll do this one I arrived. Uh Answer you just make a stop the questions. Okay? And you can just make a plug and develop FB. You don't arrived at FDA to be equal to S. F. P. Right now. Mhm. It was every equal to and yeah, thank you. Okay. It's going to be before too. Okay. Yeah. Mine was 19. Okay. Last 19. No point. It's I hope so on your team. Mhm. Okay. From this one you're gonna have that one. Of course we know the value of F. Source with ah F. B. Luggage in there. You have this one for fpD. Then you can also get your F. Source with F. G. Okay, plugging in the values here for FDA here into this equation. Yeah. Yeah. Then you are right at your eps or sweet. Okay. G. Well equal to now this this force is a member on the compression. Didn't really indicate it. Remember that compression. This is equal to 19 point it it we'll continue killer routine. So you can see a negative sign. Just remember that compression. Why plugging this value and uh into the equation for the that's direction. Okay, we have direction. Okay now this returning for this joint you have L. G. To be equal to 20 0.53. Okay. three kg newton. Yeah. Unless you can't see remember is under. And was not not attention. Uh huh. Okay. Yeah. Yeah. Yeah. Mhm. Remember is under. Thank you. So these are these are the manager of the forces. Okay. And their and their nature for the class structure.

So that's 30 degree, the center stand. So the vertical Heidi's 10 signed 30 Italy, centuries half. So that's the Heidi's fight meter and then disease. 45 degree. So if this is 45 dignity, this is fight meter, and then this distance is jen close in 30 degree. So that's five through three. So then, at the bar BC the event of the bodies five. Do fais were to spice for five. Route to that is 7.7 meter. No, In this case, we're trying to figure out what is the force that point a and full set Born C to support the 1000 nude and force acting and foreign beef. So we have some of the force in the Y direction will give us f a bus FC. It was 1000 Newton and talk about born a gwa zero will give us and see dimes fighters five. Route three It was 10,000 new 10 times five. Good three. So from here we find that and see where 6 34 new done. And then from here we find that so we find FC and then we will find that f A. It was 1000 minus 6 34 So that is 3 66 you know,

We're looking at structural analysis. Okay, consider the problem where we need to become my uh the magnitude of the forces in the member of this structure as well as their nature uh to solve this problem. Who need to apply the method of joints. But before that we need to determine the supporter uh reactions who takes so much in a moment. Okay. So much movement about a. Mhm. Mhm. Quarter zero. Mhm. Who have you do that? You're going to arrive at Almost eight times 8. Lost our E. R. Associate with reaction at E. Okay. Comes four. It was zero. You see a little half uh as it. Oh is it? Yeah. Mhm. Each time speaks, it's just it's okay. So, we're gonna have our e the reaction I eat to be equal to. Uh huh. It's still a new T. Okay, so, you can also look at reality. Take consumption of uh upward and down forces. Okay, Political forces, you are going to arrive at your reaction at D. Two equal to it is a new team. Sorry, reaction at the reaction arts. He is here 16 km. Use testicular beauty 16. Okay. And when you saw this like a little All right, but a new team. Now, we can look consider the joints. Let's look at joint uh joint A that wouldn't have uh forces. Now, we're only forces to be going out of the joint. This is joint A. For those that are coming for several that are coming in naturally. So this time This is for 50 60°. So use your the information given him being any question to become mind answers for us. E. It was never E. Okay, this one is this force going this direction. This is for A B. Going from point A. To B. E. So if we take assumption of forces in the the political direction. Yeah. Zero little arrive at F. So sweet A. D. A. Yeah. Mhm. So he will be it. Okay. Loss. S Afridi the uh sign and put it. Sorry sorry. A have some street A. B. Okay. Yeah. Yeah. Yeah. 5 60 degree. Okay. Mhm. Quarter zero. So in some of these ads on behalf so sweet baby, she's not forced to be equal to and was 9.249-4 kilo Newton. Of course this is a member. She was 9.24 kill a new team going for remember wanda compression you can see because of the negative sign is telling remember on our cooperation. Okay then we can take assumption of forces. Yeah. The assumption of forces in the horizontal direction. Yeah. We want to just now let's put a rush on what? A. Zero. Yeah, I'm going to arrive at FT. Started E. Yeah. Plus F. A. B. Causes the degree. Cool. Yeah. Oh 60 degrees 60. Mm. So I saw these ads of course you already know sort of A B. Force F. A B. Going to that member. Maybe you already know needs. So so you're going to arrive at S. E. You called people. Yeah. E. Yeah. I love money. But that's what the game B. The ram at least equal to 4.62 4.6. Thank you. two kg newton. Consider this member is under tension. Okay? Can also consider joint joint. Mhm. B. If you do that, you're gonna have the diagram who look like this. Yeah. Oh, this is a 60° based on the information given. You can figure that out. Yeah. Yeah. This is our source. Sweet B. See going from 20 to see this is absolutely speed. Yeah. Force. Okay. Came from 1st from Joint B. two E. Okay, this is F. So it would be a. Yeah. Yeah. Take some action of forces in the horizontal direction. Okay, assumption of forces in these sorry, the vertical direction to equal to zero. We're going to arrive at minus F. Yeah. Something be it people. Yeah. Be a science 60 mm. Since 16 60 degrees member. Okay, my nose. If the E. Okay. Okay, 60 degrees mm hmm. Quarter zero. Please stop this out. You're going to arrive. But F. B. B. So it should be easy to be equal to Myers S. O. B. I remember wanting to be a. So what you do dogs to give you Yeah. To eat what to 9.2 to fuckin um You team. Okay. Remember on attention. Mhm. Can go further and look at some exotic submission of forces with us and join in the no yeah, result of direction. Yeah. For the zero. You do that. You're going to have uh All right. About milo Steph. Mhm. Mhm. Mhm. You know, mm. And so ST B. C. Yeah. Sorry, the costs. Mhm mm. Yeah. Oh, 60 degrees. Okay. Anything like that? Thank you. Mhm. Yeah, cost 60 degrees. Mhm. Yeah. Most ever. Mhm. So ST B. E. host 60° 16°. Mhm. Most of for for B. C. Yeah, equal to zero. When you saw this art, you're going to arrive at F plugging values that have been gotten already into that here here in this equation, you get a source with BC Equal to -9.2, 4 months. 9.24. Yeah kilo newton. Yeah. Later's all that force is the member is under. Okay, compressive force. It's under compression. That's what I love. Then. We can also look at joint C. If you look at joint C. Mhm. We're going to arrive at this diagram. Mhm. Mhm. Mhm. 60 degrees. Mhm. Mhm. Yeah. This is 60° as well. Using the information given in the Dia ground joints should be going out of the joint. Okay. This is john C. This is F. So sweet. C. B. Came from the sea Toby. Okay. Okay. This is absolutely hcG. You can see to eat and this is F. South Street E. D. Um So you see the cd cd. Mhm. Yeah. Yeah. Well, C. To D. It. So we'll take submission of forces in the the minister. Let's go direction reporter Zero. We arrived at Milos. Uh So sweet uh C. E. Signs 60 degree mhm minus L. Surface. So you see A. D. C. D. Side. Yeah. Yeah 60 degree. Mm. Get the report zero. Mhm. Okay. Okay. We sort this out lulu have F. So you see the mhm. To be equal to F. My most earth such receive E. Therefore, yeah. You can take assumption of forces in the tourism too. Consider some of force formation of forces. Okay. The horizontal direction as well. You're going to arrive at my nose. S. A. B. C. E. Yes, consisted degree. Mhm. That call 60 degrees. Oh plus F. Most earth. Okay so the Cd consisted degree I call it, I don't think. Mhm. Look at that. Mhm. 60 degrees. Yeah. Yeah minus F. Sub receiving absolutely C. B. So all we need to do okay is to uh solve uh question. Okay. Yeah somebody quits on From one. We can call this 1 1. Okay this equation I will have here, you can call these two yeah two who served him. They don't arrive at Absolutely. C. E. Stop them plugging all the relevant values into them. So we're gonna however, S. R. C. E. To be equal to Mhm. Nine point 24. Mhm. The community mm. A lot of information and the plugging have been good. It's just plug them in your course. You sign open. you're going to have that one and you can see that this one is on the attention. Okay? That members on attention. The force then plug this value back into those equations. Anyone where you can get your F. C. D. There you arrive at -9- four. It's nine 124. Kill a new team. Okay, consider this member is under. I'm 1- four kg 19. Mhm. Cold. Okay. This member is on that compression you can see because of the negative sign. Yeah. Education then you can consider join. T Consider Joint D. If you look at 20 kinda like that we're going to have uh I'm sorry, something I look like these. Okay, I'm sorry. We have this force coming like this. And that is forthcoming. Like this is a horizontal force. So let's go to work horizontal. Yeah. Some colleagues putting from force F. E. During the week from Joint D. Is Argenti right? This one is going from 22. Uh see Okay. Mhm. Then we come because look, I just wanted is coming down. Yeah. Mm hmm. These are eight kN. eight kg newton. Uh huh. It's coming down at that joint. So we take submission of forces in the Mhm horizontal direction. Oh yeah that's fine with me forces in the horizontal direction. Big quarter zero that we're going to write about and before if so D. C. Okay that's okay. Called 60 degree. Mhm. You know. Mhm. Across 16 degrees melissa S. Starts with E. E. Yeah, because Sorry because you know, so when you solve these yellow the half F. Saw streets the E. Mhm. Waiting for too long. I was 4.62. It's four boy seeks to kilo newton. You can. Mhm. Yeah. 4162. Okay, pillow muting. Consider this is a member on the compression. So these are the forces in the members of the structure as well as their nature.

In this problem of concurrent and parallel forces. We have given that A bridge has a mass of 2.60 multiple. 10 to the power four cages. So this is envy. That is a massive bridge. 2.60 multiplied by 10 to the power four kg And 32 m long. So length age equals 32.0 m long And has a truck. That is 3500 cases Truck and 15 m from one end. What force must each end of the bridge support? So here say this is the bridge And length of this bridge is equal to 32 m. Say this is in A and say this is in the B. And the mass of this bridge equals to this age 2.60 multiplied, returned to the powerful. So wait would be equals to say here, Mass of rage multiplied with g. and the value of G is equal to 9.80 meter per second squared. So weight of the bridge CWB is equals two. 2.60 multiplier. It's 9.8. So this is equal to 25 boy for it multiply. We tend to the powerful, this is Newton and this would be acting about the sentence. So this is 24 points 25.48. multiplied by 10 to the power for Newton's. And now decided truck is 15 m from one end stay here. This is a trip. Okay, 15 m. The mass of the truck age equals 30 200 kg. This is 3500 kg. So this is 30 500 kg. That means weight of the refugee equals to em massive torque multiplier with G. So this is 3500, multiplied with This is 9.80 and this would be Newton. So, wait of the truck equals two. Here. 3.43 Multiply, we tend to the powerful Newton. And this is here, say Lord Age 3.43 multiplied, attend to the powerful Newton. And now say, here we are acting the excellent force, everyone. And here Acting Reaction Force. F. two. Now from the included um equation, we say that submission of all the force is equal to zero. That waste F one plus after. That means upward force is equal to downward force. So this is 3.43 plus 25 points for it is equal to 28.91 multiplied by 10 to the power four. Newton said this education # one. And another equation of equilibrium says that submission of all the talk should be equal to zero. That means talk in the clockwise direction, should be equal to talk in the Anti clockwise direction. And we are considering all the talk about the .8, so clockwise torque. So this is here at 16 m and the trackage is standing at 15 m from one end, so this is 15 m. So this is the point. See and this is a point today. No, the clock white or so. This is 15, multiplied with 3.43. It's equals to 51.45. So this is 51 45, and this will be a new 10 m. Bless 25, multiplied with, this is 16 is equal to 407, so this is 407 0.68 This will be new 10 m, it's equals two. F two multiplied with 32 m from here, meter to meter. Can we can sell out? And we have to evaluate the value of F two. So from here, F two equals 2 407. And this would be also power. So this would be power is also added. So this is where we tend to the power four. No, Here F two F equals to this age 459 points 13 multiply it into the powerful newton divided with 32 is equal to 14 point 3 4. So this is 14.34. multiplied by 10 to the power for Newton. And now we have to evaluate f. one. So everyone is equal to from equation one, this is 28.9. Well, multiple 10 to the power for minus F. To that age equals to 14 point 34, multiplied by 10 to the powerful Newton. From here we say that F1 is equal, so So this is equal to 14.56. So this is 14.56 multiply returned to the power for newton. Now, when we simplify it, In the real, so here F one is equal to one 456 multiplied by 10 to the power five newtons, And F two is equal to 1.434, multiplied by 10 to the power five newtons. So this is a reaction force acting at both the end.
