A 1.5" high by 2" wide rectangular bar is attached to a channel section by 3/8" diameter mach screws on 6" centers, as shown in the diagram below. The moment of inertia of the entire cros section about the horizontal neutral axis is I = 11.20 in.4 If the section transmits a vertical sh of 4 kips, determine: a) the shearing stress in the machine screws, b) the shearing stress at point A, and c) the maximum shearing stress in the cross section. 1/2"
