Why is it important for the outer wheels to rotate faster than the inner wheels during a turn?

• A. To maintain vehicle stability
• B. To ensure they can climb hills more effectively
• C. To improve acceleration
• D. To reduce fuel consumption

Answer: (A)

When a vehicle makes a turn, the outer wheels travel a longer distance compared to the inner wheels. If the outer wheels are not able to rotate faster than the inner wheels, it can lead to several handling and stability issues. Maintaining vehicle stability during a turn is crucial to prevent skidding or loss of control, which could result from the outer wheels not being able to cover more ground.

In a well-designed vehicle, the differential gear system allows for this difference in wheel speed, ensuring that the outer wheels can rotate faster. This is vital for safe and effective cornering, as it helps maintain traction and stability throughout the turn. Factors such as the distribution of weight, the speed of the vehicle, and the sharpness of the turn all contribute to how well this system functions, highlighting the importance of having the outer wheels rotating faster to ensure a smooth and stable turning experience.
