Web1 jun. 2024 · The definition of moment of inertia is definied as ∭ V r 2 ρ d V . Where r is the distance between the axis of ratation and the volume dV. In the case of a cylinder this integral will be: ρ ∫ 0 2 π d θ ∫ 0 R r 2. r d r ∫ 0 h d z. Your answer is wrong because you threated r as if it was a constant, I guess.

WebMoment of inertia of rod is given as: I = (1/3) ML 2 The distance between the end of the rod and its centre is: h = L/2 Therefore, the parallel axis theorem of the rod is: I c = (1/3) ML 2 – M (L/2) 2 I c = (1/3) ML 2 – ML 2 … Web9 sep. 2024 · For a rigid body made up of discrete particles (for example a pendulum with bob of mass m and massless rod of length l ), moment of inertia can be calculated using the formula I = ∑ i m i r i 2. For a continuous rigid body (for example a uniform solid sphere or a uniform rod etc.), I = ∫ r 2 d m. Unit of moment of inertia I is K g m 2.
WebThe moment of inertia of a hoop or thin hollow cylinder of negligible thickness about its central axis is a straightforward extension of the moment of inertia of a point mass since all of the mass is at the same distance R from the central axis. For mass M = kg. and radius R = cm. the moment of inertia is. I = kg m 2.
