Yes.

So the wheel would start spinning faster along its axis, but the rod would rotate at the same speed as before?
It gets kind of messy. mu_k is not really constant in real life.

Typically, omega_p would increase as omega_w increases.

Under certain conditions, I think the system tries to minimize the relative speed between the floor and the wheel. I believe this occurs when omega_p = (r/L)*cosθ*omega_w
