A shaft ABC of 500 mm length and 40 mm external diameter is bored for a part of its length AB, to a 20 mm diameter and for the remaining length BC, to a 30 mm diameter bore. If the shear stress is not to exceed 80 N/mm², find the maximum power, the shaft can transmit at a speed of 200 rpm. [The shear modulus is 80 GPa]. If the angle of twist in the length of 20 mm diameter bore is equal to that in the length of 30 mm diameter bore, find the lengths of the shaft that has been bored to 20 mm and 30 mm diameter. Also determine the total angle of twist.
