Tables of Second moment of inertia and mass moment of inertia are provided at the end of the assignment. Be sure that you are looking at the right table. Mass moments have units of mass length2, second moment of inertia have units of length Problem 1 (10 pts) A floor joist has a 1" hole drilled in it to accommodate a water pipe. (see Figure at left). Compare the 2nd moment of inertia of the beam about the x axis ify = 0 (the hole is in the middle of the beam) vs y 2". (Compare means to quantify the effect of the change, one way to do this is to find the percent increase/decrease of I with the change in y) 4" y 4* Section A
