You have been assigned the task of designing a flywheel capable of storing
the translational kinetic energy of a 600 kg car traveling at 100 km/hr. The
flywheel is to be manufactured out of steel and the maximum rotational
speed is 12,000 rpm.
a. Assuming that the flywheel is a uniform cylindrical disk 50 mm in
thickness, calculate the mass and diameter of the flywheel.
The Attempt at a Solution
Solving for ω[/B]
Solving for energy TKE
Solving for Ig(moment of inertia flywheel)
At this point I'm not sure how to go further.
