Let f = trackwidth/wheelbase ≠ 1
- Distance from wheel to CoM = sqrt(trackwidth^2+wheelbase^2)/2 and from now on is d
- Fydsin(angle included) = Fxdsin(other angle included) because net torque is zero.
- Fy(trackwidth/d) = Fx(wheelbase/d)
- Fx = Fy/f = Tau/rf
- |F| = |Fx + Fy| = Tau*sqrt(f^2 + 1)/rf
How did you get from step4 to step5
Divide both sides by Wheelbase/d and then… oh shoot… that should say Fx=Fyf=Tauf/r. Then F=Tau*sqrt(f^2+1)/r. Also, the answer to B should be Tau>muNr/sqrt(f^2+1)
Or you just invert the definition of f so that it is now WB/TW and then my original answers are right.
Thank you for the correction.
