I’m having trouble visualizing the wheel orientation.
It’s a standard-wheel vehicle. The wheels are not steerable. All four wheels are oriented “forward” (the front of the vehicle is labeled in the diagram).
*No, not quite that easy. But not too much harder. The vehicle is in static equilibrium. The wheels are not accelerating. Therefore, the net torque on each wheel (in the plane of the wheel) must be zero. Your solution does not satisfy this physical requirement.
It would appear that friction is trying to crush your robot into a diamond!
I know I’m doing something wrong.
I have a problem with my answer for B because I feel like Tau/R should not exceed the maximum static friction, because then there would be a lot of wheel spin, which doesn’t click for me. I also realize it’s what quinxorin already posted. I just don’t know how to do it otherwise.
See notes in red below:
Yeah, that’s what I figured. :\
Let me try again:
At equilibrium, F=muN
Tau*sqrt(2)/R=muN
Tau=muNR/sqrt(2)
If Tau is any greater, it will overcome F?

YAY! I can do physics!
