Question

A hollow shaft of internal diameter to outer diameter ratio 3
8
is to transmit 375 kW power at 100 r.p.m. The maximum torque is 20% greater than the mean. The shear stress is not to exceed 60 N/mm2
and twist in a length of 4 m not exceeds 2°. Calculate its external and internal diameters which would satisfy both the above conditions. Assume modulus of rigidity C = 0.85 × 105
N/mm2
.

Explanation:

Answer 2

Answer:

Hence torque transmitted by solid shaft is equal to the torque transmitted by hollow shaft. Similarly, 4) A hollow shaft of diameter ratio 3/8 is to transmit 375 kW power at 100 r.p.m. The maximum torque being 20% greater than the mean.
