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.

The coupled shafts shown are transmitting 270 hp at 600 rev/min. The shafts are connected by a coupling with eight bolts. The bolt circle diameters are 5 and 10 in. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. O 0 600 rev/min Determine the minimum nominal shoulder diameter of a bolt if all bolts are to have the same diameter and not exceed a shear stress of 20 kpsi Select a preferred fraction size. The minimum nominal shoulder diameter of a bolt is, in.
2. Solve the following problem Two designs for a shaft are being considered. Both have an outside diameter of 70 m and are 900 mm long. One is solid but the other is hollow with an internal diameter of 50 mm. Both are made from steel (G=120 GPa). Critically evaluate and compare the torsional shear stress, angle of twist of the two designs if they are subjected to a torque ofT 171N.m the missing Torque 171(T).
3. A 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. Determine (a) the maximum shear stress in the shaft, and (b) the angle of twist of end D relative to end A. If the desired angle of twist of end D to end A is 1°, determine (c) the power the motor should transmit considering the same rotational speed. Also, determine (d) the maximum stress in the shaft. Use G = 12 x 10 psi for steel, and assume that friction at bearing D is negligible. 4 in. 3.5 in. 3.5 in. Tmax -6 ft B C 4 ft 2 ft k ⒸD/A Tmax ⒸD/A
