A composite shaft is made by slipping a bronze tube of 3.8-in. outer diameter and 2.5-in. inner diameter over a solid steel shaft of the same length and 2.5-in. diameter. The two components are then fastened rigidly together at their ends. What is the largest torque that can be carried by the composite shaft if the working shear stresses are 10 ksi for bronze and 14 ksi for the steel? For bronze, G = 6 x 106 psi, and for steel, G = 12 x 10⁰ psi.

Composite Construction

Composite construction is the construction of structures in which two or more materials are used. Regarding structural engineering, composite construction is a construction where two materials are bound together in a technical manner such that both the materials act as a single unit to carry and transfer the load. The motives of composite construction are to increase the structural strength, make structures more aesthetic, and provide a sustainable environment.

Question

A composite shaft is made by slipping a bronze tube of 3.8-in. outer diameter and 2.5-in. inner diameter
