About Torsional Shear Stress Calculator

This tool helps mechanical engineers and students calculate torsional shear stress in shafts subjected to torque, using the polar moment of inertia formula.

Formulas Used:

• τ = (T × r) / J — Basic torsion equation
• J = πd⁴ / 32 for solid shafts
• J = π(D⁴ - d⁴) / 32 for hollow shafts

Applications:

• Design of transmission shafts
• Torsional analysis of rotating machinery
• Checking shaft safety and strength
