# Question: The figure shows a crank loaded by a force F

The figure shows a crank loaded by a force F = 190 lbf which causes twisting and bending of the ¾ -in-diameter shaft fixed to a support at the origin of the reference system. In actuality, the support may be an inertia which we wish to rotate, but for the purposes of a strength analysis we can consider this to be a static’s problem. The material of the shaft AB is hot-rolled AISI 1018 steel (Table A–20). Using the maximum-shear-stress theory, find the factor of safety based on the stress at point A.
