Tech A

b)

Tech B

a)

Control arm

b)

Rubber-bonded

c)

Spring shackle

d)

Compliance

3.

Reaction force

b)

Sprung mass

c)

Unsprung mass

Select one:

a)

Dead

b)

Straight

c)

Full-floating

d)

Semi-floating

10.

Rubber ________ and ________ stops are used to prevent direct metal-to-metal contact between the control arms and the frame if the suspension should reach its maximum limit of travel.

Select one:

a)

True

b)

False

13.
