SUMMARY
The discussion focuses on calculating the maximum torque that can be applied to a tubular shaft subjected to torsion, specifically a steel shaft with an outside diameter of 50mm and an inside diameter of 25mm. The maximum shearing stress must not exceed 70MPa. The relationship between shear stress, torque, and the polar moment of inertia is defined by the equation τ = Tc/J, where τ is the maximum shear stress, T is the maximum torque, and c is the outside radius. The polar moment of inertia is calculated using J = (π/2)(co^4 - ci^4), where co and ci are the outside and inside radii, respectively.
