Problem 6.3 - Torsional Stress

Problem Statement

Two torques are applied to a two part circular rod as shown. If T₁ = 6 kip-in., T₂ = 2 kip-in., d₁ = 5 in., and d₂ = 4 in., what is the magnitude of the maximum shear stress?

A torque is applied two part circular rod, with one end attached to the wall. The part attached to the wall has diameter d[1] and length 40 in. T[1] is applied at the intersection of the rods. The second rod has diameter d[2] and length 30 in. T[2] is applied at the free end. [Problem adapted from © Kurt Gramoll CC BY NC-SA 4.0]
