Figure P4.49 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. Make a three-dimensional Mohr circle representation of the stresses at this point. (Neglect stress concentration.)

(b) Mark on the drawing the location of highest combined torsional and transverse shear stress. Make a three-dimensional Mohr circle representation of the stresses at this point, again neglecting stress concentration.
