WebThe polar moment of inertia, J, of a cross section is an indication of a structural member's ability to resist torsion about an axis perpendicular to the section. The polar moment of inertia for a section with respect to an axis can be calculated by: J = ∫ r 2 dA = ∫ (x 2 + y 2) dA. WebTorsional rigidity, sometimes referred to as torsional stiffness, is the ability of an object to resist twisting when acted upon by an external force, torque. In mechanics of materials, torsional rigidity is the resistance to angular deformation a material has. Torsional Rigidity= Applied Torque*Length of ShaftAngle of Twist (Radians) or.
