What is the formula of moment of inertia |
|
Answer» In General form Moment of Inertia is expressed as:\xa0I = mr2\xa0and, Integral form:\xa0I = ∫dI = ∫[0→M] r2 dm⇒ The dimensional formula of the moment of inertia is given by, M1\xa0L2\xa0T0.The role of the moment of inertia is the same as the role of mass in linear motion. It is the measurement of the resistance of a body to a change in its rotational motion. It is constant for a particular rigid frame and a specific axis of rotation.Moment of inertia,\xa0I = ∑mi ri2. . . . . . . (1)Kinetic Energy,\xa0K =\xa0½ I ω2 . . . . . . . . . (2) I=mr×r |
