# Finding the angular acceleration knowing the net torque

## Homework Statement

So I worked out a problem where a uniform disk with 3 forces being applied. I found the correct net torque acting on the disk. Now the problem is asking me to find the angular acceleration.

r= I*(ang.acc^)2

## The Attempt at a Solution

I made the assumption that you could use this formula. Plug the net torque in and calculate the moment of inertia and solve. Is this true?

You mean T=Iα ?

Yes this is what you essentially need to do.

ah yup. But the symbole is an r I thought. Is this correct?
