Flywheels are large, massive wheels used to store energy. They can be spun up slowly, then the wheel's energy can be released quickly to accomplish a task that demands high power. An industrial flywheel has a 1.6 m diameter and a mass of 270 kg. Its maximum angular velocity is 1600 rpm. A motor spins up the flywheel with a constant torque of 56 Nm. How long does it take the flywheel to reach top speed? How much energy is stored in the flywheel? The flywheel is disconnected from the motor and connected to a machine to which it will deliver energy. Half the energy stored in the flywheel is delivered in 2.4 s . What is the average power delivered to the machine?
