## Homework Statement

An electric motor turns a flywheel through a drive belt that joins a pulley n the motor and a pulley that is rigidly attached to the flywheel. The flywheel is a solid disk with a mass of 80.0kg and a radius R = 0.625m. It turns on a frictionless axle. Its pulley has much smaller mass and a radius of r = 0.230m. The tension Tu in the upper (taut) segment of the belt is 135N, and the flywheel as a clockwise angular acceleration of 1.67rad/s^2. Find the tension in the lower (slack) segment of the belt.

## Homework Equations

I don't even know how to start solving this. Our textbook goes over the basic definitions of torque, but I have no idea how to apply this to a circumstance such as this to find Tension.

## The Attempt at a Solution

Well, since I don't even know how to start, I guess I would find the torque as a result of the tension forces? I would appreciate if you could explain how I would start this question, as our textbook is next to useless here.
