the friction between moving part of the machine can be dash by putting some machine oil on the path
Answers
Answer:
first this is the right question - the friction between moving parts of the machine can be dash by putting some machine oil on the path
Explanation:
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
Methods for decreasing friction:
Make the surfaces smoother. Rough surfaces produce more friction and smooth surfaces reduce friction.
Lubrication is another way to make a surface smoother. ...
Make the object more streamlined. ...
Reduce the forces acting on the surfaces. ...
Reduce the contact between the surfaces.
Methods of reducing friction
1)Friction can be reduced by making the surface smooth by polishing.
2)Friction can be reduced by applying lubricants (like oil or grease) to the rubbing surface.
3)Friction can be reduced by using wheels to move objects.
4)Friction can be reduced by using ball bearing between the moving parts of machine.
Answer:
When a car screeches round a bend at high speed, the only thing that stops it skidding is the friction between its tires and the road—a force that can be several times greater than its weight. Here friction is working like a kind of glue that sticks the car to the road, but it's not always so helpful. Under the hood, friction is busily wearing out the engine parts—it's one of the main ways that a car wastes energy. That's why we need lubricants: substances that fight friction and allow moving machine parts to slide past one another more smoothly.
