Title Measuring the moment of inertia of a flywheel. Objective Measure the angular velocity of a flywheel and use conservation of energy to calculate its moment of inertia. Apparatus Flywheel String Slotted mass on hanger Stop-watch Vernier caliper Metre ruler Theory The rotational kinetic energy can be defined by the equation K=1/2 I ?2. Where I is the moment of inertia of the body about the axis of rotation. In this experiment, the flywheel rotates freely about a horizontal axis. The radius of the axle of the flywheel can be measured with a caliper. As m falls, its gravitational potential energy is transferred into translational kinetic energy of m, rotational kinetic energy of the flywheel and work done by friction. As the flywheel completes N further turns, its original rotational kinetic energy is transferred into friction loss. Assume the flywheel decelerates uniformly. Thus, the moment of inertia of the flywheel can be determined. Procedure 1. The flywheel was set as shown with the axle of...
