Question: In Problem, failure of the specimen occurs at a torque = 1200 N-m and a corresponding angular deflection =10°. What is the shear strength of the metal?
Problem: A torsion test specimen has a radius = 25 mm, wall thickness = 3 mm, and gage length = 50 mm. In testing, a torque of 900 N-m results in an angular deflection = 0.3°. Determine
(a) the shear stress,
(b) shear strain, and
(c) shear modulus, assuming the specimen had not yet yielded.
