Force of friction and Torque

  1. Nov 14, 2011 #1
    Given a plot of Torque vs Angular acceleration, would it be valid to say that the slope of that line would be the Rotational inertia and the Y intercept to be equal to the force of friction?

    I think there could be an argument for the Y intercept being the force or TORQUE due to friction. what do you think?

    What would you use for your argument?

    Ʃτ=Iα => τ-τf=Iα

    rearrange and compare with y=mx+c
