My questions is reasonably simple and requires no difficult equations, just a lot of puzzling over (for me at least).
OK, Consider a rubber mat of mass 10Kg and an area of 1m^2 in contact with the ground. The maximum frictional force that exists between the mat and the ground is force F.
Now if you were to fold the mat exactly in half, so that the area in contact with the ground is now 0.5m^2 but everything else stays equal, what is the new frictional force that exists between the mat and the ground? Is it 2F, is it 0.5F or is it still F?
