Thank you for the help. I understand the question now.
KERPS: kinetic energy recovery system in cars
My guess to the questions above:
When it spins too fast, there will be a bigger frictional force.. Energy will be lost quickly.
When you slow it down to fast, Torque is too huge and breaks...
Homework Statement
Describe and explain some of the design features of a flywheel in order for it to store
maximum energy. Your answer should include consideration of the flywheel’s shape,
the material from which it is made and its design for high angular speeds.
