[***Bonus Problem 2***] A circular bar with diameter of 2 inch and length of 20 inch is fixed at the end A. The bar is loaded at the other end by a downward force of F = 2 kip, a centrically compressive force P = 64 kip, and a torsional moment T = 20 kip · in. (10' in total) 1) Find the position B (determine the distance away from the fixed end) on the top of the shaft for which the stress state is pure shear in the established xyz-system. (6) 2) Is there any point C on the bottom of the shaft for which the stress state is also pure shear in the established xyz-system? If so, find such position C. If not, explain your reason. (4) X = ? B x = ? x Ρ
