Problem: A flywheel of mass 185 kg has an effective radius of 0.63 m (assume the mass is concentrated along a circumference located at the effective radius of the flywheel).
Problem I: How much work is done to bring this wheel from rest to a speed of 119 rpm in a time interval of 28.9 s?
kJ
Problem II: What is the applied torque on the flywheel (assumed constant)?
Nm
Please keep solution short and simple and please no copy and paste. Thanks.
