Torsion. A 40-mm diameter, 533-mm length shaft is drilled, for a part of its length L₁, to a 20 mm diameter and for the remaining length L2 to a 30 mm diameter drill hole. If the allowable shear stress is 85 MPa, find the maximum power that the shaft can transmit at a speed of 235 rev/min. If the angle of twist in the length of 20 mm diameter drill hole is equal to that in the 30mm diameter drill hole, find the length of the shaft that has been drilled to 20 mm and 30 mm diameter.
