WebJo = 𝙸z = 𝙸x + 𝙸y. Where. 𝙸x = Moment of inertia about the x-axis. 𝙸 y = Moment of inertia about the y-axis. Therefore by finding the moment of inertia about the x and y-axis and adding them together we can find the polar moment of inertia. To know how the polar moment of inertia is different from the moment of inertia, read our ...

WebMoment of inertia definition. The product of the area ( or mass ) and the square of the distance of the C. G. of the area ( or mass ) from an axis is called the moment of inertia of the area ( or mass ) about that axis. It is represented by I. hence moment of inertia about the X-axis is represented by Iₓₓ whereas about Y-axis represents Iyy.
