Question

Required information The cantilevered bar in the figure is made from a ductile material and is statically loaded with Fy=380 lbf and Fx = Fz=0. The diameter Dis 3 in and the height his 3.5 in. Lengths AB and BC are 6 in. and 5 in., respectively. Determine the magnitudes and directions for all stresses acting on the critical stress element. (Transverse shear may only be neglected if you can justify this decision.) The transverse shear stress is psi. The bending stress is psi. The torsional shear stress is psi.
