101201 LAW OF PARALLEL AXESĪxis XX and axis YY are passing through centre of gravity of the body. Let, ( I_ \right ). What will be the moment of inertia of the given rectangle about an horizontal axis passing through the base 1500 mm 1650 mm 1666 mm 1782 mm. Moment of inertia of a body about an axis which is parallel to an axis passing through the centre of mass of the body is equal to the sum of moment of inertia of body about the axis passing through centre of mass and product of area or mass and square of the distance between the two axes.Ĭonsider about a body of area ( A ) as shown in figure.
