    6.2 Friction. Friction is a contact force that opposes the motion or attempted motion between two systems. Simple friction is proportional to the normal force N supporting the two systems.; The magnitude of static friction force between two materials stationary relative to each other is determined using the coefficient of static friction, which depends on both materials.

  • Types of Bearings - How Bearings Work |

    In a ball bearing, the load is transmitted from the outer race to the ball, and from the ball to the inner race. Since the ball is a sphere, it only contacts the inner and outer race at a very small point, which helps it spin very smoothly.But it also means that there is not very much contact area holding that load, so if the bearing is overloaded, the balls can deform or squish, ruining the ...

  • How can I measure the coefficients of friction of pulleys?

If your system of sheaves is 33% efficient, you still have 3 to 1 at the winch. This would require 3' pulleys or a little bigger.
