Inertia of rectangle formula
WebThe polar moment of inertia, J, of a cross-section with respect to a polar axis, that is, an axis at right angles to the plane of the cross-section, is defined as the moment of inertia of the cross-section with respect to the point of intersection of the axis and the plane. WebFundamentally, the moment of inertia is the second moment of area, which can be expressed as the following: I x = ∫ ∫ y 2 d A. I y = ∫ ∫ x 2 d A. To observe the derivation of …
