The cantilevered bar in the figure is loaded with Fy = 250 lbf and Fx = Fz = 0. Analyze the stress situation at just right of A (smaller cross-section) by obtaining the following information. (a) Determine the precise location of the critical stress element at the cross section at just right side of A . (b) Sketch the critical stress element and determine magnitudes and directions for all stresses acting on it. (Transverse shear may be neglected.) (c) For the critical stress element, determine the principal stresses and the maximum shear stress by using Mohr's circle.
