Circular moment of inertia formula
WebFeb 2, 2024 · Define if you want the polar moment of inertia of a solid or a hollow circle. For a solid circular section, use the polar moment of inertia formula J = πR⁴/2, where R is the radius, and J is the polar moment of inertia. For a hollow circle, the polar moment of inertia is given by J = π(R⁴ - Rᵢ⁴)/2 *, where Rᵢ is the inner radius.
