Energy System
An energy storage system based on a flywheel (a spinning disc) can store a maximum of 3.7 when i driving?
System energy storage based on a flywheel (rotating disk) can store a maximum of 3.7 when the wheel rotates to 1.5 × 104 revolutions per minute. What is the moment of inertia of the flywheel? Answer must be in kg / m ^ 2 * thanks
Kinetic energy of a rotating body = 0.5 Iw ^ 2 where I = moment of inertia w = angular velocity. w = 2 * pi * 1.5 × 10 ^ 4 / 60 = 1570 rad / s I = 3.7 / (0.5 * 1570 ^ 2) = 3 * 10 ^ 6kg-m * 2
