Web4 jun. 2024 · We have our general formula for the moment of inertia I = \int_0^M r^2 dm. I = ∫ 0M r2dm. We now have to identify what dm dm is. Since the rod can be looked at in one dimension dm = \frac {M} {L} dr dm = LM dr where L L is the length of the rod. \frac {M} {L} LM can be looked at as an one dimensional density for the rod. WebMoment of Inertia Formula. In General form Moment of Inertia is expressed as I = m × r2. where, m = Sum of the product of the mass. r = Distance from the axis of the rotation. and, Integral form: I = ∫dI = ∫0M r2 dm. ⇒ The dimensional formula of the moment of inertia is given by, M 1 L 2 T 0.
