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. Polar Moment of Inertia also known as the second polar moment of area is a quantity used to describe resistance to torsional deformation. It is denoted as Iz or J.
Web24 Apr 2024 · for which by Newton’s second law of motion we need a force F = m a t = mr α. This force in turn generates a torque of magnitude (5.4.1) τ = r ⋅ F = m r 2 α. The last equality is reminiscent of Newton’s second law of motion, but with force replaced by torque, acceleration by angular acceleration, and mass by the quantity m r 2.
