The shaft in the figure below is part of a drive for an automated transfer system in a metal stamping plant. Gear Q delivers 30 hp to gear B. Sheave D delivers the power to its mating sheave as shown. The shaft carrying B and D rotates at 550 rpm. Use SAE1040 cold drawn steel. Note: Torque on gear at B and the torque on sheave at D are equal. Gear Data: - NB= 96 (Number of teeth on gear B) - Pd= 6 (Diametral pitch for gear B) - Spur gears Gear pressure angle =20o - Shaft at B and D rotate at 550 rpm. Use the following assumptions: - Bearing seats have sharp fillets. Kt=2.5 - Design factor (Factor of Safety) = 3 - Pinion Q is rotating in CCW direction. - Cs= Size factor = 0.80 a) Determine the magnitude of the torque in the shaft at all points b) Compute the forces acting on the shaft at all power-transmitting elements c) Compute the reactions at the bearings

Gear Data:
- NB= 96 (Number of teeth on gear B)
- Pd= 6 (Diametral pitch for gear B)
- Spur gears Gear pressure angle =20o
- Shaft at B and D rotate at 550 rpm.
Use the following assumptions:
- Bearing seats have sharp fillets. Kt=2.5
- Design factor (Factor of Safety) = 3
- Pinion Q is rotating in CCW direction.
- Cs= Size factor = 0.80
