Final answer:
The force that primarily impacts the development of traction-enhancing tires by companies like Nissan and Toyota, in collaboration with Michelin, is friction (B). It allows the vehicle to grip the road and safely move, turn, and stop. Friction is also utilized in many other contexts where good grip is essential.
Step-by-step explanation:
When Nissan and Toyota collaborate with companies like Michelin to develop tires, they are focusing on enhancing the traction of the tires. Traction is directly related to the force of friction. This force is what allows the tires to grip the road, enabling the vehicle to move forward, turn, and stop safely. The maximum static friction that helps prevent tires from slipping is given by the coefficient of static friction (μs) multiplied by the normal force (N). When a car is on level ground, the normal force (N) is equal to the mass of the car (m) times the acceleration due to gravity (g). Therefore, the essential force for maintaining traction and ensuring the tires last longer, thereby enhancing the driving experience, is primarily friction (B).
For example, when a car is on a level ground curve, friction acts to keep the car from slipping and acts as the centripetal force. The strategy when designing tires is to ensure they provide enough friction to counteract any other forces that may cause the car to lose traction, such as the downhill component of gravity when a vehicle is going downhill, or the opposing forces acting on it in different driving conditions.
Friction is not only important in vehicles, but also in other applications where a good grip or hold is needed, such as in athletic equipment or in footwear for better performance and safety.
