A flywheel consists of a 100kg cylinder of radius 25cm. How large a torque(constant) must a motor apply to bring the flywheel up its maximum speed of 1500 rpm in 100 revolutions. What is the average power of this motor?
3. For Grading Knight 12.64 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 1.5 m diameter and a mass of 250 kg. Its maximum angular velocity is 1200 rpm. a. A motor spins up the flywheel with a constant torque of 50 Nm. How long does it take the flywheel to reach...
A flywheel has a mass of 5.0 kg, inner radius of 8.00 cm, and outer radius of 14.2 cm. Determine a) angular frequency to store 400 kJ of rotational energy b) the average power and torque delivered by the flywheel if 400kJ can be stored in 6.67 s
Some European trucks run on energy stored in a rotating
flywheel, with an electric motor getting the flywheel up to its top
speed of 160 π rad/s. One such flywheel is a solid, uniform
cylinder with a mass of 270 kg and a radius of 1.07 m. (a) What is
the kinetic energy of the flywheel after charging? (b) If the truck
uses an average power of 6.2 kW, for how many minutes can it
operate
between chargings?

Trucks can run on energy stored in a rotating flywheel with an electric motor getting the flywheel up to its top speed of 847 radians per second. The flywheel is a solid, uniform cylinder with a mass of 461 kg and a radius of 0.939 meters. If the trucks uses an average power of 8.0 kW, for how many minutes can it operate before the flywheel needs to be "charged" again? By "charging" we mean the electric motor adds energy...
A high-speed flywheel in a motor is spinning at 500 rpm when a power failure suddenly occurs. The flywheel has mass 43.0 kg and diameter 72.0 cm . The power is off for 34.0 s and during this time the flywheel slows due to friction in its axle bearings. During the time the power is off, the flywheel makes 150 complete revolutions. At what rate is the flywheel spinning when the power comes back on? How long after the beginning...
A grinding wheel is a uniform cylinder with a radius of 8.70 cm and a mass of 0.600 kg.(a) Calculate its moment of inertia about its center.( kg·m2)(b) Calculate the applied torque needed to accelerate it from rest to 1500 rpm in 3.00 s if it is known to slow down from 1500 rpm to rest in 59.0 s.( m·N)

please explain ur answer.
rotating flywheel. The car a car that makes use of energy stored in a we were to design 8. Suppose is "charged" by using flywheel is a solid homogeneous cylinder with energy of the flywheel after it's been "charged" up? (b) If the car needs to operate with an average power of 8.13 kW, for how many minutes can it operate between chargings? an electric motor to get the flywheel up to its top speed of...
