Re: Physics Quiz 6
Part A:
1. Fy=Tau/r
2. Distance from wheel to CoM = sqrt(trackwidth^2+wheelbase^2)/2 and from now on is d
3. Fydsin(angle included) = Fxdsin(other angle included) because net torque is zero.
4. Fy(trackwidth/d) = Fx(wheelbase/d)
5. Fx = Fy/f = Tau/rf
6. |F| = |Fx + Fy| = Tau*sqrt(f^2 + 1)/rf
Part B:
1. muN<Tau*sqrt(f^2+1)/rf
2. Tau>muNrf/sqrt(f^2+1)
