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. FAQ
WebThe unit of moment of inertia is a composite unit of measure. In the International System (SI), m is expressed in kilograms and r in metres, with I (moment of inertia) having the dimension kilogram-metre square. In the U.S. customary system, m is in slugs (1 slug = 32.2 pounds) and r in feet, with I expressed in terms of slug-foot square.
