Problem 68P

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. A motor spins up the flywheel with a constant torque of 50 N . m. How long does it take the flywheel to reach top angular speed of 1200 rpm?

Problem 68P

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. A motor spins up the flywheel with a constant torque of 50 N . m. How long does it take the flywheel to reach top angular speed of 1200 rpm?

ANSWER:

Step 1 of 3

 

Here we have to find the time required to reach the top angular speed of 1200 rpm.

The diameter of the flywheel is 1.5 m.

The radius is,

.

The mass of the flywheel is,

.

The torque given to the flywheel is,

.

.

We know that,

.

So,

.
