Shown below is a picture of a Go-Kart which weighs 300# (with the rider), distributed with 60% of the weight on the rear axle and 40% on the front axle. The weight from the GoKart is applied to the rear axle at two bearings, as shown by the arrows below. The axle is fabricated from steel (E=30x106 psi) and has a 1.25" outer diameter with a .125" wall thickness. a. Draw the shear and moment diagrams for the axle. You may assume that the axle is simply supported. b. Determine the location (i.e., location on the axle) and magnitude of the maximum bending stress. Draw a cross-section of the axle, indicate the neutral axis, and mark the position of the maximum tensile stress on the cross-section. c. Using superposition, determine the deflection of the axle half way between the two bearings (i.e., 14" from one bearing, as shown).

Question
Shown below is a picture of a Go-Kart which weighs 300# (with the rider), distributed with
60% of the weight on the rear axle and 40% on the front axle. The weight from the GoKart
is applied to the rear axle at two bearings, as shown by the arrows below. The axle is
fabricated from steel (E=30x106 psi) and has a 1.25" outer diameter with a .125" wall
thickness.
a. Draw the shear and moment diagrams for the axle. You may assume that the axle is
simply supported.
b. Determine the location (i.e., location on the axle) and magnitude of the maximum
bending stress. Draw a cross-section of the axle, indicate the neutral axis, and mark the
position of the maximum tensile stress on the cross-section.
c. Using superposition, determine the deflection of the axle half way between the two
bearings (i.e., 14" from one bearing, as shown).
