Torsion / Shaft Stress

Maximum shear stress and angle of twist for a solid or hollow circular shaft under torque. Shear stress is highest at the outer surface and zero at the center.

T T r τ max at surface shaft length L, torque T at each end
Circular shaft in torsion; cross-section inset shows radius r.
