Determine the bending (o-, ) and shear stress ( Tx), ) at the surface element shown on the solid circular shaft below. Use Mohr's circle to determine the principle stresses, a l , 62 , the maximum shear stress on the element, rim, , and the angle, zero, among the plane shown and the plane of principle stresses. Use the following data
F = 20 kips
d = 16 in
L = 6 ft
c = 3 in
E = 29000 ksi
G = 11200 ksi
