An automobile engine supplies power, P= 190 hp, at a rotational speed of 4000 rpm to a driveshaft. If the allowable shear stress in the driveshaft must be limited to allow = 5.00 ksi, determine: (a) the minimum diameter required for a solid driveshaft. (b) the maximum inside diameter permitted for a hollow driveshaft if the outside diameter is D = 2.50 in. (c) the percent savings in weight realized if the hollow shaft is used instead of the solid shaft.
