Q 1-3 Determine the maximum tensile, compressive, and shear stresses at point A on the bicycle pedal crank shownin the figure. The pedal and crank are in a horizontal plane and point A is located on the top of the crank. The load P = 160 lb acts in the vertical direction and the distances (in the horizontal plane) between the line of action of the load and point A are b, = 5.0 in. and b, = 2.5 in. Assume that the crank has a solid circular cross section with diameter d = 0.6 in.
