SUMMARY
To calculate the power required to turn a flywheel at a constant angular velocity, use the formula Energy = 1/2 * I * ω², where I is the moment of inertia and ω is the angular velocity in radians per second. For a flywheel with a diameter of 24 inches, width of 5 inches, and mass of 50 kg, the moment of inertia I can be calculated using I = m * r², with r being the radius. If there are no losses such as friction or air resistance, no power is needed to maintain constant angular velocity.
