Two different Aluminum E 70 GPa v033 tubular crosssections a

Two different Aluminum (E 70 GPa, v-0.33) tubular cross-sections are proposed for an engineering application to support a 250 N.m torque. If the length of each tube is 0.75 m, find average shear stresses in various segments of the cross-section and the angular twist of each tube. Evaluate the mechanical performance of each tube by comparing your results.

Solution

The answe of following question is as follows .

The value ofaverage shear stress is 98 kn/m2. These are the calculated results.
