| 1. | Regarding the sliding case, the friction force is given.
|
| 2. | From that, you can roughly calculate the friction forces of the car.
|
| 3. | There are two contact surfaces, each with its own normal and friction force.
|
| 4. | In this type of support, normal force and friction force can become significant.
|
| 5. | What if we now consider internal friction forces?
|
| 6. | Surprisingly, the friction force does not depend on the surface area of common contact.
|
| 7. | This friction force is thus given by:
|
| 8. | However at higher speeds the centrifugal force is added to the friction force to make L.
|
| 9. | Stick-slip can also be observed on the atomic scale using a friction force microscope.
|
| 10. | These friction forces are generated by the extreme tightness of the structural bolts holding the connection together.
