Problem 8.21

It was stated in Sec. 8.3 that the shearing stresses produced in ashaft by the transverse loads are usually much smaller than thoseproduced by the torques. In the preceding problems their effectwas ignored and it was assumed that the maximum shearing stressin a given section occurred at point H (Fig. P8.21a) and was equalto the expression obtained in Eq. (8.5), namely,Show that the maximum shearing stress at point K (Fig. P8.21b),where the effect of the shear V is greatest, can be expressed as where b is the angle between the vectors V and M. It is clear thatthe effect of the shear V cannot be ignored when tK \$ tH. (Hint:Only the component of M along V contributes to the shearingstress at K.)
