Consider the following statements: A 4-wheel vehicle moving a sharp circular path at high speed will 1. Overturn about its outer wheels 2. Overturn about its inner wheels 3. Skid outwards 4. Skid inwards Which of these statements are correct?

When a 4-wheel vehicle moves on a sharp circular path at high speed, it experiences a strong centrifugal force acting outwards, away from the center of the turn. 1. Overturn about its outer wheels: The outward centrifugal force creates a moment that tends to lift the inner wheels. If this force is strong enough, the vehicle will overturn, pivoting around its outer wheels (the wheels on the side away from the center of the turn). This statement is correct. 2. Overturn about its inner wheels: This would imply an inward force causing the vehicle to tip towards the center, which is contrary to the effect of centrifugal force. This statement is incorrect. 3. Skid outwards: If the centrifugal force exceeds the maximum static friction between the tires and the road, the vehicle will lose grip and slide outwards, away from the center of the turn. This is a common phenomenon when taking a turn too fast. This statement is correct. 4. Skid inwards: Skidding inwards would mean sliding towards the center of the turn, which does not happen due to centrifugal force. This statement is incorrect. Therefore, statements 1 and 3 are correct.
