What is torsional moment?

In the field of solid mechanics, torsion is the twisting of an object due to an applied torque. Torsion is expressed in either the Pascal (Pa), an SI unit for newtons per square metre, or in pounds per square inch (psi) while torque is expressed in newton metres (N·m) or foot-pound force (ft·lbf).

How to Calculate Torsional moment on shaft given shear stress?

Torsional moment on shaft given shear stress calculator uses Torsional moment on shaft = Torsional shear stress in twisted shaft*Polar moment of inertia for circular section/Radial Distance from Axis of Rotation to calculate the Torsional moment on shaft, Torsional moment on shaft given shear stress formula is defined as a moment that twists a structure. Unlike axial loads that produce a uniform, or average, stress over the object's cross section, a torque creates a distribution of stress over the cross-section. Torsional moment on shaft is denoted by τ symbol.

How to calculate Torsional moment on shaft given shear stress using this online calculator? To use this online calculator for Torsional moment on shaft given shear stress, enter Torsional shear stress in twisted shaft (𝜏), Polar moment of inertia for circular section (J) & Radial Distance from Axis of Rotation (r) and hit the calculate button. Here is how the Torsional moment on shaft given shear stress calculation can be explained with given input values -> 5.3E+7 = 35000000*3.8E-08/0.025.
