Mass moment of inertia of slender bar
WebThe moment of inertia of a point mass is given by I = mr 2, but the rod would have to be considered to be an infinite number of point masses, and each must be multiplied by the … WebIt is given as; I G = ∫ r 2 dm. Mass moment of inertia is also used in different rigid body rotation problems. These include; ( ΣM G = I G α ) F = ma analysis moment equation. ( T = ½ I G ω 2 ) Rotational kinetic energy. ( H G = I G ω ) Angular momentum. Mass moment of inertia units are kg.m 2 and lb.in 2.
