Question 2: Determine the maximum tensile, compressive, and shear stresses at point A and B on the bicycle pedal crank shown in the figure.

Question 2: Determine the maximum tensile, compressive, and shear stresses at point A and B on the bicycle pedal crank shown in the figure. The pedal and crank are in a horizontal plane and point A and B are located on the top of the crank. The load acts in the vertical direction and the distances (in the horizontal plane) between the line of action of the load and point A are b1 and b2 and b3 mm. Assume that the crank has a solid circular cross section with diameter .
