AUT104 Week 6 Quiz

Unsprung mass includes all of these, EXCEPT:

• wheel and tire assemblies.

• nonindependent axle.

• frame/chassis.

• outboard brake assemblies.

When a wheel and tire assembly hits a speed bump, the assembly moves upward.

Select one:

• True

• False

Tech A says that one purpose of the suspension system is to keep the tires in contact with the road. Tech B says that the heavier the weight of the unsprung components, the smaller the reaction force they will generate. Who is correct?

Select one:

• Tech A

• Tech B

• Both A and B

• Neither A nor B

Tech A says that yaw is when a vehicle deviates from its straight path. Tech B says that roll is felt during hard braking. Who is correct?

Select one:

• Tech A

• Tech B

• Both A and B

• Neither A nor B

The suspension system performs all of the following functions EXCEPT:

Select one:

• absorbing the large road forces generated while driving on non-perfect roads.

• holding the wheels and tires in the proper orientation.

• monitoring the tread wear of each tire.

• supporting the weight of the chassis, drivetrain, passenger compartment, occupants, and any additional load.

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.

Select one:

• Upward force

• Downward force

• Reactive force

• Applied force

The three terms pitch, roll, and yaw describe the movement of a vehicle around three axes labeled X, Y, and Z. Technician A says that roll occurs when the vehicle is being braked. Technician B says that yaw occurs in a vehicle when the vehicle is being drifted. Who is correct?

Select one:

• Technician A

• Technician B

• Both Technician A and Technician B

• Neither Technician A nor Technician B

The ________ is all the parts of the vehicle that are not supported by springs, including the components that follow the road contours, such as wheels, tires, axles, and outboard brake assemblies.

Select one:

• Reaction force

• Sprung mass

• Unsprung mass

• Weightless area

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

Select one:

• Cornering force

• Driving thrust

• Braking torque

• Deflecting force

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

Select one:

• Leaf spring

• Coil spring

• Torsion bar

• None of the above
