When lubricating parts that do not have a grease relief port, inject grease until A. The boot splits
B. Grease begins to escape from the base of the boot
C. The boot swells slightly
D. The part won't hold any more

C. The boot swells slightly

Explanation:

Friction can be defined as a force that opposes the motion of an object in relation to another.

This ultimately implies that, friction is the opposition to the relative motion of two objects in contact. Therefore, lubrication (lubricants) are used to prevent friction between moving parts.

Generally, grease relief port are created by manufacturers of mechanical parts so as to prevent over-lubrication.

However, when lubricating parts that do not have a grease relief port, inject grease until the boot swells slightly so as to maintain the seal at the ball joints.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?
