Similar to linear kinetic energy, rotational kinetic energy depends on the moment of inertia I and the square of the angular velocity ω as K=1/2Iω2. When the moment of inertia and/or the angular velocity changes, the new rotational kinetic energy is just the original multiplied by a factor mm, such that Knew=mK. What is the multiplication factor mm when the moment of inertia increases to 21I and the angular velocity reduces to 0.2ω? Give the formula first then solve.
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? How much torque does the flywheel exert on the machine?
The wheel in the figure has eight equally spaced spokes and a radius of 47 cm. It is mounted on a fixed axle and is spinning at 3.0 rev/s. You want to shoot a 27-cm-long arrow parallel to this axle and through the wheel without hitting any of the spokes. Assume that the arrow and the spokes are very thin.

While spinning down from 500.0 rpm to rest, a solid uniform disk does 51 KJ of work. If the radius of the disk is r=400mm what is it's mass?.
Delivery trucks that operate by making use of energy stored in a rotating flywheel have been used in Europe. The trucks are charged by using an electric motor to get the flywheel up to its top speed of 1,000.0rad/s. One such flywheel is a solid disc, rotating about its central axis, with a mass of 1,010.0kg and a radius of 1.2m. What is the kinetic energy (in J) of the flywheel after charging?
Computation. A concept car includes a solid disk-shaped flywheel which can be spun up to store rotational kinetic energy. On demand, that stored energy can be converted into the car's translational kinetic energy. Suppose the flywheel has a mass of 343 kg, a radius of 0.3 m, and maximum rotational speed of 56 rev/s. Calculate the 1,566-kg car's maximum speed (starting from) rest if all of its kinetic energy comes from the flywheel. [Tip: Be careful with units.] Vmax = m/s Record your numerical answer below, assuming three significant figures. Remember to include a "-" as necessary.
e One way to store energy is in the rotational motion of a flywheel, and some have proposed using suchtechnology to power automobiles.
