1. The problem statement, all variables and given/known data I am trying to figure out how to determine a vehicle's translational acceleration given a torque at the wheels so that I can determine what effect wheel diameter and mass will have on the ultimate translational acceleration. 2. Relevant equations F = Ma I*alpha = Torque I = .5mr^2 3. The attempt at a solution Torque = I*alpha = .5*m*a*r^3 a = (Torque*2)/(m*a*r^3) I think I know how to find the translational acceleration of a rolling wheel, but how can I relate this to the total acceleration of a vehicle with a mass? Also, there are 4 wheels (only 2 are supplied with a torque). Do I need to think about this as well? Thanks for the help.
