when is friction undesirable?​

Sagot :

NAOTOMORI27IN

Friction between moving parts in machines is undesirable, because the moving parts rub against each other, heat up, and wear out. Friction can be reduced by lubricating the surfaces.

Hope it helps

Answer:

Without friction,you would not be able to walk,the wheels on a vehicle would have no grip on a road surfacing and the vehicle would not be able to move forward.On the other hand ,friction is undisirable in most of the cases.

Friction causes mechanical part to seize and wear out.
