Final answer:
The best way to get good traction on hard-packed snow is to equip your vehicle with winter or snow tires. Winter tires have a unique tread pattern and rubber compound designed to provide better grip on snow and ice. Another example of where more friction is desirable is in the braking system of a car.
Step-by-step explanation:
The best way to get good traction on hard-packed snow is to equip your vehicle with winter or snow tires. Winter tires are designed with a unique tread pattern and rubber compound that provides better grip on snow and ice compared to all-season or summer tires.
The deeper and wider grooves on winter tires help channel away snow and slush, allowing the tires to maintain contact with the road surface. Additionally, winter tires have softer rubber that stays pliable in cold temperatures, providing better traction.
Another example where more friction is desirable is in the braking system of a car. When you apply the brakes, the pads or shoes of the brake system create friction with the rotors or drums, slowing down or stopping the vehicle. The more friction that can be generated between the brake components, the better the braking performance of the vehicle.
