A solid circular bar is fixed at point A. The bar is subjected to transverse load V

Question:

A solid circular bar is fixed at point A. The bar is subjected to transverse load V = 70 lb and torque T = 300 lb-in. at point B. The bar has a length L = 60 in. and a diameter d = 3 in. Calculate the principal normal stresses and the maximum shear stress at element 1 located on the bottom surface of the bar at fixed end A (see figure). Assume that element 1 is a sufficient distance from support A so that stress concentration effects are negligible.
