Shaft design is one of the most critical tasks in any rotating machine. You work as a reliability engineer for an automation company and your boss asked you to validate existing design parameters of a rotating 0.015-m-diameter solid shaft and pully assembly, shown in Figure.5. This task can be performed by: 1. Calculating the maximum torsional stress and deflection angle in the shaft. (P2) 2. Find the torsional component of strain energy Utorsion: (M3) 3. Use the torsional Castigliano's Theorem to evaluate the shaft's deflection. (M3) 4. If at point Ba groove was made (See Figure) with a radius r=0.00107 m and span d=0.0143 m, find the value of the maximum stress induced by stress concentration at this groove. (P3) Use for Part 4 of the question only! 0.050 m 300 N B 0.250 m 200 N 550 N 0.250 m 400 N 0.150 m D 0.075 m y Figure.5: Solid shaft and pully assembly Shaft design is one of the most critical tasks in any rotating machine.
