If a car is moving forward, what is the direction of the moment of the moment caused by the rotation of the tires?
  • a)
    It is heading inwards, i.e. the direction is towards inside of the car
  • b)
    It is heading outwards, i.e. the direction is towards outside of the car
  • c)
    It is heading forward, i.e. the direction is towards the forward direction of the motion of the car
  • d)
    It is heading backward, i.e. the direction is towards back side of the motion of the car
Correct answer is option 'A'. Can you explain this answer?

When you curl your wrist in the direction in which the tires are moving then you will find that the thumb is pointing outwards. That is outwards the body of the car. This phenomena is also observed in rainy seasons. When cars travel on the roads, the water is thrown outside from the tires, due to moment.

Explanation:

The moment caused by the rotation of the tires is known as the rolling resistance moment. This moment is caused due to the friction between the tires and the road surface. When a car is moving forward, the direction of the rolling resistance moment is towards the inside of the car. This is because of the following reasons:

• The tire and the road surface are in contact with each other at the bottom of the tire. Due to this contact, a force is generated in the opposite direction of the motion of the car. This force is known as rolling resistance force.

• The rolling resistance force causes a moment around the axis of rotation of the tire. This moment is known as the rolling resistance moment.

• The direction of the rolling resistance moment is towards the inside of the car. This is because the force acting on the tire is in the opposite direction of the motion of the car. So, the moment generated by this force is in the direction towards the inside of the car.

Conclusion:

Hence, the correct option is A, which states that the direction of the rolling resistance moment is towards the inside of the car when it is moving forward.
