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.

Direction of the Moment caused by the rotation of the tires

The moment caused by the rotation of the tires of a moving car is an important concept in understanding the dynamics of the vehicle. The direction of this moment depends on various factors such as the type of tire, the friction between the tire and the road surface, and the motion of the car.

Explanation:

When a car is moving forward, the tires rotate in a forward direction as well. The moment caused by this rotation is generally referred to as the rolling moment. It is important to note that the rolling moment is a result of the friction between the tire and the road surface.

Direction of the Rolling Moment:

The direction of the rolling moment can be determined by considering the contact patch between the tire and the road surface. The contact patch is the area where the tire makes contact with the road.

Inwards direction:

In the case of a car moving forward, the rolling moment caused by the rotation of the tires is directed inwards, towards the inside of the car. This means that the moment tends to rotate the car in a direction that would cause it to turn towards the inside of the curve.

This can be explained by considering the forces acting on the tire. As the tire rotates, it generates a lateral force due to the friction between the tire and the road surface. This lateral force acts towards the center of the turn. The moment caused by this force tends to rotate the car inwards, causing it to turn towards the inside of the curve.

Summary:

In summary, when a car is moving forward, the moment caused by the rotation of the tires is directed inwards, towards the inside of the car. This rolling moment is a result of the friction between the tire and the road surface and tends to rotate the car in a direction that would cause it to turn towards the inside of the curve.
