1. The problem statement, all variables and given/known data
I have a plot whose vertical intercept is 0.00352 [Nm] If the bearings are 2 [mm] from the center of the wheel, then what is the force of friction? Use three significant figures for your answer in Newtons. 2. Relevant equations Torque= (Rotational Inertia)(Angular Acceleration)+ Torque due to friction 3. The attempt at a solution Torque=0.00352Nm Torque due to friction = (Rotational Inertia)(Angular Acceleration)  Torque Tf= (I)*(A)0.00352Nm I don't even know how to attempt to solve for those other variables. Is this even the right equation to use?
