Prob. 4.3-10. The solid circular shaft of diameter d in Fig. P4.3-10a has a twist rate of dd/dx = 0, under the action of the torque T. If the solid shaft is replaced by a tubular shaft with a ratio of outside diameter to inside diameter of d/d, = 1.2 but weighing the same as the solid shaft (Fig. P4.3-10b), by what percentage would the torque have to be increased in order to produce the same twist rate 6, in the tubular shaft?
