Question

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 1.9 m diameter and a mass of 260 kg . Its maximum angular velocity is 1400 rpm .

1.How much energy is stored in the flywheel?

2.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 2.2 s . What is the average power delivered to the machine?

3.How much torque does the flywheel exert on the machine?
