For the beam cross section shown, assume bf = 5.6 in., tf = 0.52 in., d = 11.2 in., tw = 0.41 in., and yH = 2.8 in. Calculate (a) the moment of inertia for bending about the z axis. (b) the value of Q associated with point H. (c) Consider the section as a solid 5.6 in. x 11.2 in. rectangle with two smaller rectangles cut out to form the I shape. Determine the area moment of inertia for the solid 5.6 in. x 11.2 in. rectangle (without the two smaller rectangles cut out) about the z axis. Answer: I1 = in.4
