Question

It is required to design a square key for fixing gear on a shaft of 50 mm diameter. 14 KW power at 317 rps is transmitted from the shaft to the gear. Determine the applied Torque in N-m It is required to design a key for fixing gear on a shaft of 50 mm diameter. It is required that 15 kW power at 720 rpm is to be transmitted from the shaft to the gear. The yield strength of the key material is 500 MPa and the factor of safety is 3. Determine the design shear stress in the key in MPa It is required to design a key for fixing gear on a shaft of 50 mm diameter. The applied torque is 292 N-m. The Shear stress of the Key Material is 84 MPa and the factor of safety is 3. The standard key dimension for a 50-mm-diameter shaft would be 14 mm X 9 mm Determine the minimum length of the key in mm to resist shear stress. It is required to design a key for fixing gear on a shaft of 50 mm diameter. The applied torque is 333 N-m .The design compressive stress of the Key Material is 139 MPa and the factor of safety is 3. The standard key dimension for a 50-mm-diameter shaft would be 14 mm X S9 Determine the minimum length of the key in mm to resist compressive stress.
