I did an experiment in school and we located the end of the cord on the pin, which is situated on the shaft of the flywheel. Carefully I winded the cord onto the shaft, so that it is not ‘crossed over’ or trapped.
the hanging mass weighed 1.5kg on the free end of the cord (holding the flywheel stationary),i then raised or lowered the hanging mass to a measured distance of 1.5m. there is no motor its pulled by the hanging mass
Then I Released the flywheel and using a stopwatch, record the time taken for the hanging mass to reach the floor was 22.45 seconds.
The diameter of flywheel shaft is 25.45mm
Total mass of flywheel is 32.7 kg

Calculate
(a) Inertia
(b) The Frictional force
(c) The Torque
(d) Work done
(e) The power dissipated (average and maximum)
(f) The centripetal force
(g) The centripetal acceleration
