Energy is to be stored in a 70.0-kg flywheel in the shape of a uniform solid disk with radius R = 1.20 m. To prevent structural failure of the flywheel, the maximum allowed radial acceleration of a point on its rim is 3500 m/s2. What is the maximum kinetic energy that can be stored in the flywheel?

Solution 45E Step 1: Given data: Mass of flywheel M = 75.0 kg Radius of solid disk R = 1.25 m 2 The maximum allowed radial acceleration of a point on its rim is a max = 3500 m/s
