Finding the angular acceleration knowing the net torque

  1. Nov 2, 2011 #1
    1. The problem statement, all variables and given/known data
    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.

    2. Relevant equations
    r= I*(ang.acc^)2



    3. 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?
