Sarah analysis. Consider the diagram uh in the world we want to become mine. Uh the value the magnificat forces uh in a member of that uh system trust. Okay. Now, as well as to determine your nature. Now to solve this kind of a problem, you can see that the angle this angle is not given to be difficult for us to uh do something. So we need to find this angle. Okay, They will probably call the method of joints to solve the problem. All right. So to get an angle apply, don? T to use Danuta were able to get that angle, but So that about two. So what about value gets to take the James Acton. Okay, at of That value of 1.5. About two. So when you do that, you're going to arrive at Toyota equal to mm 36 0.9 degrees. Okay, now we can go ahead. We can now consider joint C. God Syria will have see there. Okay, Consider there's a force coming down. There is 45. That is our P if you want. It's 45. Mhm kilo newton. I see. But of course there's a first come down there From them. Take that so called this one. Fc is going towards the so called FcD and this one is coming towards this terrible. So these are the assumptions that go to that the direction. So let's call this Fc happy because it's moving towards a big. Okay, so we consider submission of uh forces in the region to direction. Okay, they're going to arrive at consider we have that for the FcB. The fact is the only force there. Zero. So One of the forces zero. Silicon go ahead. You can call this equation question one. So, if we take submission of forces in the tourism to in the vertical direction. Okay? Yeah, they're going to arrive at You can see that we have 45 commuting coming down 45 kilometers. And we also have a love uh we have um FcD. Okay. F C D. F. C. D. Of see the Okay. All right. Equal to zero. So when you do that, you can see that you're going to arrive. You solve this where you're going to have your FCD to be equal to minus 45. Yeah. Killer Newton. Now that tells you that the nature of this force it is in congress on our conclusions. Okay. So because as you would see. Okay, so, we got in the nature of down on the regular force as well as in nature. Okay. All right, so we can continue with another joint. So let's go to the mess joint. So, we have a joint D. The first one is joined. C. Okay with joint Joint you can see so let's look at joint deep. So john D. Okay. Mhm. So, you have this force going up there. This is our 20 I mean, you Andy mm we have this force coming in. This is actually joined a force going out like this. So this force will call it because it's going to ask it quality, the detail here, They will call this force this p. two. Yeah. Which is equal to at this point starting keeping beauty. Yeah, he's given any questions and now you have this course this is F. D. C. Okay. All right. And there's enough force coming up like this. This is of baby. Okay, So you cannot take uh assumption of forces along the horizontal direction. Do that zero. I want to have Values like these 13 plus and the every A plus. Uh the B. Of course you can most 36 29 degrees sequel to zero. So what was we can just go ahead and look for solution of forces in the uh that's a cool direction. Look at the solution of forces in the So you can call this question three. Yeah, we have some other equations before. Okay, This one is an equation push on to. Okay, We already have a crucial one. So, if you saw this one, so for this one, submission of forces in the very cool direction. We have mhm. It will be F. D. C. It lost, I. M. D. B. Sign. Yeah, that's six point nine degrees. Yeah. Okay, You have that equal to zero. All right. When you stop these and you plug in your your MPC have already gotten before. Okay, somebody's remember that. We've gotten every see before. So you can you arrive at your f. d. b equal to 75 one Yes kilo routine. If you consider for this force is positive for so this is attention is on the attention, remember. Okay, for that particular member. Okay, So I've gotten three of the forces now Stayed on the job. Now if we use the question three, we are going to arrive plugging values and gotten into equation three. Okay, well, envelope FDP there we are going to arrive at F the to be equal to my nose 19. Kill a new team. And see the nature of this force is a compression. So we have been able to uh fine determine the magnitude of the members. Okay, reinforces in the members of the structure of the trust as well as Yeah, nature.
