3-86* Repeat Prob. 3-84 with Fx = 300 Ibf, Fy = 250 Ibf. and Fz = −100 Ibf.
3-84* The cantilevered bar in the figure is made from a ductile material and is statically loaded with Fy = 250 Ibf and Fx = Fz = 0. Analyze the stress situation in the small diameter at the shoulder at A by obtaining the following information.
- (a) Determine the precise location of the critical stress element at the cross section at A.
- (b) Sketch the critical stress clement and determine magnitudes and directions for all stresses acting on it. (Transverse shear may be neglected if you can justify this decision.)
- (c) For the critical stress clement, determine the principal stresses and the maximum shear stress.
