Determine the maximum tensile, compressive, and shear stresses at point A on the bicycle pedal crank shown in 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 hori- zontal plane) between the line of action of the load and point A are b₁ = 5.0 in. and b₂ = 2.5 in. Assume that the crank has a solid circular cross section with diameter d = 0.6 in. P = 160 lb Crank d-0.6 in. b₁ = 5.0 in. b₂ = 2.5 in.
