When any two objects are in contact, at least one type of force is acting on the contact point, friction. Friction can cause wearing of material and generate heat. To minimize the effects of friction, a lubricant is used to partially separate the two objects.
"Explain the purpose of lubrication.
Define sliding, rolling, and fluid friction.
State the factors that affect lubrication.
Explain the differences between hydrodynamic, hydrostatic, and boundary lubrication.
Discuss the importance of viscosity in lubricant selection.
