What is Polar Moment of Inertia?

Polar Moment of Inertia is a measure of an object’s capacity to oppose or resist torsion when some amount of torque is applied to it on a specified axis. Torsion, on the other hand, is nothing but the twisting of an object due to an applied torque. Polar moment of inertia basically describes the cylindrical object’s (including its segments) resistance to torsional deformation when torque is applied in a plane that is parallel to the cross-section area or in a plane that is perpendicular to the object’s central axis.

How to Calculate Moment of Inertia about Polar Axis?

Moment of Inertia about Polar Axis calculator uses Polar Moment of Inertia = (pi*Diameter of Shaft^(4))/32 to calculate the Polar Moment of Inertia, The Moment of Inertia about Polar Axis formula is defined as a measure of an object's resistance to changes in its rotation, providing a way to quantify the distribution of mass within an object and its resulting rotational inertia. Polar Moment of Inertia is denoted by J symbol.

How to calculate Moment of Inertia about Polar Axis using this online calculator?
