What is the dual role of friction in race cars?

• It only helps in stopping the car.

• It only helps in speeding up the car.

• It is both beneficial and detrimental.

• It has no effect on race cars.

Why is managing brake temperature crucial at short tracks like Martinsville?

• Because the brakes cool down too quickly.

• Because the brakes are used less frequently.

• Because the brakes are not needed at all.

• Because the brakes can overheat and lose effectiveness.

How do teams monitor brake rotor temperatures during practice?

• By using a pressure gauge.

• By using a stopwatch.

• By using a thermometer.

• By using temperature-sensitive paint.

What is the optimal temperature range for racing tires?

• 350 to 400 degrees Fahrenheit.

• 300 to 320 degrees Fahrenheit.

• 200 to 250 degrees Fahrenheit.

• 400 to 450 degrees Fahrenheit.

Why are racing tires wider than passenger car tires?

• To improve fuel efficiency.

• To reduce friction.

• To increase speed.

• To help dissipate heat better.

What role does oil play in the engine of a race car?

• It only lubricates the tires.

• It increases friction.

• It reduces friction and heat.

• It has no effect on friction.

What can happen if there is no lubrication between the piston and the bore?

• The engine components may weld together.

• The engine will run faster.

• The engine will cool down.

• The engine will produce less smoke.
