Q. After a puncture a driver is attempting to remove a wheel nut by applying a force
of P KN to one end of a wheel brace as shown in Fig. 1. In cross-section the brace
is a hollow steel tube (see section aa) of internal diameter r mm and external
diameter q mm.

(a) Calculate (i) the twisting moment, (ii) the bending moment, and (iii) the shear
force in the brace at position S due to the applied load P.
(b) Calculate (i) the shear stress due to twisting, and (ii) the bending stress at
position S. Note that the shear force will not produce any shear stress at S.
(c) Calculate the maximum shearing stress in the brace at position S using the
Maximum Shear Stress Criterion.
