HW 5 / Due Oct 15 / Chapter 6 - 9 (there are zero force members!), 53, 65, 87, 102

For problem 65: Draw a free body of the top section (A-F). One of the counters (CJ and HE) will be a zero-force member, as the counters are too slender to act in compression. You solve the problem by assuming one of them to be zero-force and seeing if the other member is in tension. If it isn't, assume that the other one is zero-force and solve again.

HW 7 / Due Oct  18 / Chapter 9 - For the problem figure announced in class, determine I_x, I_y, J_o, k_x, k_y, A, the location of the centroid (x-bar and y-bar), and the moments about axes through the centroid.
