What is the difference between static friction and rolling resistance?
Now that you mention it, that's true. But for example, in this page make an analysis and turns out that M=mg*(sinθ+cosθ*μr)*R - the maximum static friction is added. This analysis only considers forces, and then derives the motor torque. Shouldn't I reach the same result? And you can also find...- googly_eyes

I'm sorry, I fail to see how that term appears if you take momentum with respect to the center of mass. The worst case scenario, correct?- googly_eyes

Can Online Forums Help Solve Scientific Problems?
Hi! Trying to solve a problem that's been giving me a headache, and nobody has had the patience to explain it to me :( But there seems to be other rather interesting forums aswell, after I finish with this ordeal I might give them a peek :p- googly_eyes

What is the difference between static friction and rolling resistance?
Hi, it's probably a frequent question, but I can't seem to wrap my hear around. I'm trying to understand how I reach that value, not just how to get the value. I'm designing a vehicle with 4 wheels. It'll climb a surface with a slope theta (in degrees). This is the FBD that I've come up with of...- googly_eyes
