WebSep 9, 2024 · 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. Dimensional Formula = [ M 1 L 2 T 0] Now, let’s look at the moment of inertia for different shapes, but before we do that, let’s review the parallel axis and perpendicular axis theorem. WebQuestion: PHYS 2x11: Moment of Inertia Purpose: To measure the moment of inertia of some common shapes and to compare with that of the theoretical models. Apparatus: 1. computer and interface; 2. Rotational Apparatus and Smart-pulley System. Theory: The angular acceleration of a rigid body is proportional to the net torque applied to the rigid …

WebMay 26, 2005 · 2. Ok divide this problem into two parts . First find the moment of inertia of complete disc (without any part cut) about the origin. Now find MI of the cut out part about the origin using parallel axis theorem. For the second part , you will have to find out mass of cutout part,this can be easily done as the disc is uniform , use unitary method. WebThe moment of inertia of an object is a determined measurement for a rigid body rotating around a fixed axis. The axis might be internal or external, and it can be fixed or not.
