 Moment Of Inertia Of Flywheel Aim : The aim of this experiment is to measure the moment of inertia of a flywheel. Diagram : Materials : -   A heavy flywheel mounted on an axle on suitable bearings. -   A ruler Vernier calipers -   Thin cord Stopwatch Procedure : -   Set up the apparatus as shown in the diagram and allow the weight to fall a height h. -   The length of twine fixed to the small mass should be equal to h, the original height of the    small mass above the ground. -   Measure the time (t) it takes to hit the ground. -   Count the number of revolutions (N0) before the weight hits the ground and the further    number of revolutions (Nf) before the flywheel comes to rest. -   Repeat the procedure several times and obtain mean values for all quantities. -  Measure the diameter of the axle (d) and record the mass of the falling weight (m) Conclusion : You can calculate the moment of inertia (I) of the flywheel from the formula, I = md2 / 4 x Nf / [Nf + N0] x ([gt2 / 2h] - 1)
