a) State FOUR factors that affect the effectiveness of hydrodynamic lubrication as a means of reducing friction between components.
b) Under what conditions would boundary lubrication be used rather than hydrodynamic lubrication and what would cause this to happen?
c) Briefly describe THREE uses of lubricants other than for lubrication.
Friction: When a body moves or tends to move over the other body, a force opposing the motion develops at the contact surfaces. This force that opposes the movement or the ten
