A Car Has a Mass of 930 Kg Has Wheels

question 33

Multiple Choice

A car has a mass of 930 kg has wheels with a radius of 35 cm, and the distance between the axles is 3.1 m. The coefficient of static friction between the tires and the road is 0.52. It is equipped with anti-lock brakes so that the tires do not slide when it is braking. If the weight of the car is supported equally by the four tires, what is the total torque on the tires exerted by the forces between the tires and the horizontal road when there is maximum braking, i.e. when the tires are about to slip?

• A)1.2 × 10² N m
• B)1.7 × 10³ N m
• C)1.2 × 10⁴ N m
• D)1.6 × 10² N m
• E)1.4 × 10⁴ N m

Definitions:

Power Divider

A component in vehicle drivetrains, particularly in heavy trucks, used to distribute power evenly across multiple axles.

Forward Differential

A differential gear arrangement that allows the driven wheels to rotate at different speeds, typically located at the front of vehicles with front-wheel drive.

Drive Torque

The force that causes rotation in a vehicle, typically measured at the drive wheels, which directly impacts acceleration.
