T Friction mass is the amount of hanging mass needed to spin the object at constant angular velocity (net torque = zero, acceleration = zero). Under this condition the torque from friction is equal and opposite the torque from the hanging 'friction mass'.

Using your equation from above, calculate the experimental value of the rotational inertia of the Ring + Plate + Sensor together. Remember to subtract off the mass required to overcome friction (friction mass) from the hanging mass. a. Experimental Rotational Inertia of (Lg Ring + Plate + Sensor)
