Question

Question: In Problem, the specimen fails at a torque = 8000 ft-lb and an angular deflection = 23°. Calculate the shear strength of the metal.

Problem: In a torsion test, a torque of 5000 ft-lb is applied that causes an angular deflection =1° on a thin-walled tubular specimen whose radius =1.5 in, wall thickness = 0.10 in, and gage length = 2.0 in. Determine

(a) the shear stress,

(b) shear strain, and

(c) shear modulus, assuming the specimen had not yet yielded.
