Q8. A compound shaft consists of a 25 mm thick bronze sleeve fitted over a 375 mm diameter steel shaft. The compound shaft transmits 2.9 MW at 92 rev/min. Calculate EACH of the following:

(a) The torque transmitted by the bronze sleeve;

(b) The torque transmitted by the steel shaft;

(c) The maximum shear stress in the bronze sleeve;

(d) The maximum shear stress in the steel shaft.

Note: Modulus of Rigidity of the steel = 80 GN/m²

Modulus of Rigidity of the bronze = 45 GN/m²
