Torsional Deflection of Solid Cylinder Calculator

In solid mechanics, torsion is the twisting of an object due to an applied torque. It is expressed in newton metres (N·m) or foot-pound force (in·lb). In sections perpendicular to the torque axis, the resultant shear stress in this section is perpendicular to the radius.
