Dhaval Rana Physic HN January 22, 2009 Objective- To determine the moment of inertia of a rotating body from its angular acceleration Moment of inertia, also called mass moment of inertia or the angular mass is a measure of an object's resistance to changes in its rotation rate. It is the rotational analog of mass. That is, it is the inertia of a rigid rotating body with respect to its rotation. The moment of inertia plays much the same role in rotational dynamics as mass does in basic dynamics, determining the relationship between angular momentum and angular velocity, torque and angular acceleration, and several other quantities. While a simple scalar

Unformatted text preview: treatment of the moment of inertia suffices for many situations, a more advanced tensor treatment allows the analysis of such complicated systems as spinning tops and gyroscope motion. For this lab, we formed a system with a platter, hanging mass, and other objects to be placed on the pulley. Now, the purpose of this lab is to find the moment of inertia of the rotating object from its angular acceleration. We were given the objects’ mass and dimensions and by using the photo gate system and we were given the linear velocity of all four of the object. The calculations of the lab are explained in the next page. Possible errors:...
