The cantilevered bar in the figure is made from a ductile material and is statically loaded with Fy =200 lbf and Fx = Fz = 0. Analyze the stress situation in rod AB by obtaining the following information. (a) Determine the precise location of the critical stress element. (b) Sketch the critical stress element and determine magnitudes and directions for all stresses acting on it. (Transverse shear may only be neglected if you can justify this decision.) (c) For the critical stress element, determine the principal stresses and the maximum shear stress. 1-in dia. in 2 in 5 in 5 in
