For the handle in Prob. 380, one potential failure mode is twisting of the flat plate BC.

Question:

For the handle in Prob. 3–80, one potential failure mode is twisting of the flat plate BC. Determine the maximum value of the shear stress due to torsion in the main section of the plate, ignoring the complexities of the interfaces at B and C.

In Prob. 3–80, 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.
