Torsional shear stress: Definition, Formula, Calculation

The shear stress in the shaft may be resolved into principal stresses via Mohr's circle. If the shaft is loaded only in torsion, then one of the principal stresses will be in tension and the other in compression. These stresses are oriented at a 45-degree helical angle around the shaft. If the shaft is made of brittle material, then the shaft will fail by a crack initiating at the surface and propagating through to the core of the shaft, fracturing in a 45-degree angle helical shape. This … Webτ = T r / J (1) where. τ = shear stress (Pa, lbf/ft2 (psf)) T = twisting moment (Nm, lbf ft) r = distance from center to stressed surface in the given position (m, ft) J = Polar Moment of … Web4) TORSIONAL STRAIN equals torsional stress (t) divided by torsional modulus of elasticity (G). See Figure F. g = 2 x e@ 45° = t/G t = Mt(d/2)/J where torsional stress (t) equals torque (Mt) multiplied by the distance from the center of the section to the outer fiber (d/2), divided by (J), the polar moment of inertia.
