Torsion for a Circular Shaft Calculator

The torsion for a circular shaft expresses the relationship between the applied torque and the resulting shear stress in the material.

• $\tau$ is the shear stress in the circular shaft,
• $T$ is the applied torque (torque is a twisting force),
• $r$ is the radial distance from the center of the shaft to the point where shear stress is being calculated,
• $J$ is the polar moment of inertia of the circular cross-section.
