Consider an inclined plane with angle $x$. Now put a cylinder on top of it and consider three different cases.
- A the limiting frictional force $f$ is greater than $mg\sin(x)$ where $m$ is the mass of cylinder.
- B the limiting friction $f$ is exactly equal to $mg\sin(x)$
- C it is less than $mg\sin(x)$.
What will happen in each case?
In A and B I suppose $f$ will provide torque and then friction will change direction to oppose the angular velocity maybe.
In C it will start moving and then provide torque but the friction should vanish although it stays there and apparently it may or may not cause slipping. What is meaning of slipping?
I am not sure about these cases. Can someone explain. I just need physical intuitive explanation.
