PROBLEM NO. 1 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 80 MPa, find the maximum power that the shaft can transmit at a speed of 230 rev/min. If the angle of twist in the length of 20 mm diameter drill hole is equal to that in the 30 mm diameter drill hole, find the length of the shaft that has been drilled to 20 mm and 30 mm diameter.

Write legibly and box the final answer.
The motor A delivers 3000 hp to the shaft at 1500 rev/min, of which 1000 hp is removed by gear B and 2000 hp is removed by gear C. 1.) Determine the maximum shear stress in the shaft in ksi. (Answer in 2 decimal places) 2.) Determine the angle of twist in degrees of end D relative to end A. Use G = 12 x 106 psi for steel, and assume that friction at bearing D is negligible. (Answer in 3 decimal places)
