I know, by mathematical arguments, moment of inertia of a particle is $$ I = \text{mass} \cdot r^2.$$ But what is the physical reason? When I want the other linear equivalents like velocity,acceleration, we only multiply the linear component times the distance from the …
WebFor a particle P at a distance r from O, its moment of inertia about the axis X1OX1′ is equal to m r 2. The moment of inertia of the whole body about the axis X1X1′ is given by, I0 = Σ mr2 …. (1) From the point P, drop a perpendicular PA to the extended OG and join PG. In the ΔOPA, OP 2 = OA2 + AP 2. r2 = (x + h)2+AP 2. WebI c = moment of inertia about the center. M = mass of the body. h 2 = square of the distance between 2 axes. Let us see how the Parallel Axis Theorem helps us to determine the moment of inertia of a rod whose axis is …
