A) full film
B) photographic film
C) plastic film
D) partial film

Answer 3

A

Question 4

Extreme pressure (EP) chemicals are added to lubricants to break up deposits that form on metal components due to exposure to elevated temperatures.

Question 5

Lubricants are classified into several different categories which include: mineral, vegetable, and ________.

A) synthetic
B) animal
C) petroleum based
D) All answers are correct

Question 7

Tribology is the study of tribal life in south America.

Question 8

Synthetic compounds are created from multiple chemical reactions of discrete atoms or molecules to form a final molecule with the desired characteristics.

Question 9

Viscosity index is the _________________.

A) resistance of fluid molecules to move relative to each other
B) measure of the oils stability with changes in temperature
C) origin of the oil base stock
D) ability to be used for road paving

Question 11

Grease is considered a plastic fluid due to the change in viscosity that occurs when it is stressed.

Question 12

Mixed film condition prevents component wear by eliminating metal on metal contact and uses the lubricant to reduce heat buildup

Question 13

Emulsion means that two liquids or a solid and liquid do not mix but one of them will stay suspended in the other.

Question 14

Frictional force is the force between bodies in contact that resists their motion.

Question 15

Lubricants made from a Paraffinic crude oil base stock have a relatively high viscosity index.

Question 16

Lubricants come in a variety of forms such as: solid, semisolid, liquid, and __________.

A) brown
B) tribology
C) gas
D) graphite

Question 19

Oil analysis is a good preventative maintenance tool to determine the condition of the lubricant and the components being lubricated.
