Q1. Figure shows a hand crank with static vertical load applied to the handle. (a) Copy the drawing and mark on it the location of highest bending stress. (b) Mark on the drawing the location of highest combined torsional and transverse shear stress. (c) Calculate the maximum normal and shearing stresses at point A. (d) Estimate the safety factor with respect to initial yielding, according to the maximum distortion energy (von Mises) theory. The steel has yield strength of 200 MPa.
