AUT-104 Chapter 40

If a wheel and tire are very light, they will not generate as much ________, so it is easier for the spring to push them back down, maintaining contact with the road. 

• Upward force 

• Downward force

• Reactive force

• Applied force 

________ refers to the lateral movement of the axle housing during turning. 

• Cornering force

• Driving thrust 

• Braking torque 

• Deflecting force 

________ is movement around the vehicle's y-axis, commonly felt during hard braking or fast acceleration, when the front of the vehicle noses down or rises up slightly. 

• Pitch 

• Yaw

• Roll

• Elasticity 

Compliance bushings are: 

• metallic, bronze or brass

• plastic honeycomb. 

• fiberglass reinforced

• molded with voids

Some shock absorbers: 

• use hydrogen gas to provide cushioning

• use pressurized nitrogen gas to reduce aeration of the hydraulic fluid

• use argon gas to cool the fluid

• use inert gas to aerate the hydraulic fluid to provide more cushioning

All the following are true about multi-leaf springs, EXCEPT: 

• they use rebound clips to keep the leaves in alignment

• they have a main leaf with spring eyes rolled at each end for connection to the frame. 

• they are held together with a center bolt.

• they are best for vehicles carrying light loads

Tech A says that a dead axle is designed to carry the weight of the vehicle, with no drive capability. Tech B says that live axles transmit power to the wheels. Who is correct? 

• Tech A

• Tech B

• Both A and B

• Neither A nor B

The MacPherson strut suspension system can be used on only the rear of the vehicle. 

• True

• False

Tech A says that on short-/long-arm (SLA) suspension systems, the upper control arm is the long one. Tech B says that on SLA suspension systems, the control arms are connected to the frame by ball joints. Who is correct? 

• Tech A

• Tech B

• Both A and B

• Neither A nor B

What type of spring is mounted on a strut suspension system?
