Auto Tech 4

The suspension system is designed to ________________

• Hold the tires on the car
• absorb road shock and vibrations
• keep the car from running off the road
• carry large loads of materials

Unsprung weight refers to the vehicle parts not supported by springs like:

• the doors, seats dashboard
• the engine, drive train
• the wheels, tires, brake and steering assemblies
• the trunk, roof and frame of the car

The unsprung weight should be kept:

• as high as possible
• evenly distributed
• balanced to the back of the car
• as low as possible

Metal springs, rubber, and air all work to provide suspension system support by:

• absorbing some amount of force
• evenly distributing force from the front to the back of the car
• continually moving the most weight in the car
• adding weight in the car when necessary

Springs react to road shock by:

• Immediately returning to their original state until the energy is dissipated
• continually stretching and flexing
• moving very little overall
• not fluctuating at all

What car part fluctuates in length or oscillates until the energy from the road shock is dissipated?

• Shocks
• Tires
• Springs
• Tie rods

Vehicle movement may be due to:

• yaw
• pitch
• roll
• all of these

All of the following are correct about a solid axle, EXCEPT:

• It is also known as a beam axle
• It is often supported by leaf springs
• It is a very simple axle that mounts the hubs and wheel units
• It is a type of independent suspension

All of the following are types of shocks, EXCEPT:

• gas pressurized
• air shock
• rack and pinion type
• twin-tube type

Technician A says a control arm can be formed in a wishbone design. Technician B says some control arms can be formed in a flexible design referred as fore-arms. Who is correct?

• Technician A
• Technician B
• Both A and B
