What is the general purpose of a wheel assembly?

• To increase the vehicle's weight

• To smoothly roll over irregular surfaces to enable vehicle mobility

• To reduce the vehicle's weight carrying capacity

• To increase sliding friction

What do rolling wheels do in terms of friction and weight carrying capacity?

• Increase sliding friction and reduce weight carrying capacity

• Reduce sliding friction and reduce weight carrying capacity

• Increase sliding friction and increase weight carrying capacity

• Reduce sliding friction and increase weight carrying capacity

What function do wheels have related to steering a vehicle?

• They transfer the rolling vehicle weight from the tires to the hubs to steer a vehicle

• They increase the vehicle's speed for better steering

• They solely provide the force needed to steer without transferring weight

• They have no role in steering a vehicle

What does the combined stress from the force of driving torque and vehicle weight signify for a wheel used in a non-driving position?

• It means increased friction and reduced mobility

• It means the same wheel can be used in both driving and non-driving positions without any difference

• It means the wheel is not suitable for use in a vehicle

• It means the same wheel used in a non-driving position

Which of the following is NOT a factor determining the design, construction, and selection of wheels?

• Loading rate

• Color of wheel

• Position of wheel

• Tire size

What is considered when selecting a wheel for a specific application?

• Tire type

• The brand of the wheel

• The price of the wheel

• The color of the vehicle

Which factor is important for the maintenance and standards of wheels?

• Wheel system

• Type of braking system

• Maintenance and standards

• Applications

What are the two basic types of wheels used by medium- and heavy-duty (HD) buses and trucks?

• Alloy wheels and steel wheels

• Open center or demountable rim and disc wheels
