We want to reduce friction in order to increase dash
Answers
Explanation:
You know that friction produces heat. That's why rubbing your hands together makes them warmer. But do you know why? Friction causes the molecules on rubbing surfaces to move faster, so they have more energy. This gives them a higher temperature, and they feel warmer. Heat from friction can be useful. It not only warms your hands. It also lets you light a match as shown in the Figure below. On the other hand, heat from friction between moving parts inside a car engine can be a big problem. It can cause the car to overheat.
How is friction reduced between the moving parts inside a car engine?
To reduce friction, oil is added to the engine. The oil coats the surfaces of the moving parts and makes them slippery. They slide over each other more easily, so there is less friction.
