Homework Help: Moment of Inertia Lab

  1. Apr 12, 2008 #1
    1. The problem statement, all variables and given/known data
    How much frictional torque is there? I know angular acceleration and torque applied. (I do not know if this can be used to find torque friction, though.)

    2. Relevant equations

    3. The attempt at a solution

    I know that Frictional torque can be found by doing Torque net - Torque applied. But I do not have torque net, which is another part of the lab where I use the frictional torque found to find the torque net.

    The net external torque of a rigid body is equal to the product of the angular acceleration and moment of inertia of that body.
