Elliot Marshall PHYS 103L-04 Rotational Dynamics Objective: Using torque, angular acceleration, and transitional motion we will find out the moment  of inertia of a wheel about its axle and take into account the friction on the ball bearings at its  axle. Apparatus: Bicycle wheel with a string around its rim and a small pulley attached to its axle with  another string around it, masses, stopwatch, meter stick, caliper. Procedure: Part 1:   First we tested the inner wheel by attaching a mass of 50 grams to the string on  the inner pulley, measuring the height of the mass, and then timing how long it took for the mass  to fall to the ground when released.  We did four trials with each mass and 8 different masses.  The masses and times were recorded. Part 2:   Then we tested the outer rim of the wheel by doing the same thing as in  Part 1  except we used the string on the outer rim of the wheel and we started with 20 grams.

Part 3:   A piece of red tape was placed on the rim of the wheel and then the wheel was  spun.  We counted how many revolutions it took for the wheel to stop and how long it took to do  so. Data: Object Mass (kg) Rim 0.893 Spoke 0.007298 Total Spokes (36 spokes) 0.2627 Total 1.1557
