Question

A hollow shaft, having an internal diameter 50% of its external diameter, transmits 600 kW at 150 rpm. Determine the external diameter of the shaft if the shear stress is not to exceed 65 N/mm2 and the twist in a length of 3 m should not exceed 1.4 degrees. Assume maximum torque = 1.2 times the mean torque and modulus of rigidity = 1 × 10 5 N/mm

Answer 1

Answer:

Explanation:

The shearing stress in a solid shaft is not to exceed 45 N/mm2 ... a hollow circular shaft of external diameter 30 cm and internal diameter 15 cm if the ... 5.7 N/mm2] A solid circular shaft is to transmit 375 kW at 150 r.p.m. (i) Find the ... whose internal diameter equal to 2/3rd of its external diameter, the length, the ...
