i wonder if you mean when is friction not useful ?
well; it is useful when you require a surface to hold onto another item .
such as the clutch and brake components in a car.
a clutch depends on the friction of the metal surface of the clutch plate to drag against another surface to disengage the drive mechanism .
A brake system needs the friction between fibre brake shoes and metal case to slow down a car-- vehicle .
this is useful.
however , in some areas of a car there are parts that require very little friction,
such as wheel bearing and inlet and exhaust timing valves which control the operation of fuel ignition timing within engine compartment .
these component's have a limited amount of friction but depend upon a coolant such as lubrication oil to ease this friction - action .
with an increase in thickness -- measurements the clearances will become less and hence the friction will increase to cause excess heat production .
this will cause undesirable heat effect, and expansion and wear and quite likely overheating .

Is friction useful?
yes friction is very useful because it help objects not to slide or slip
Is one way that friction is useful?
stopping cars Friction is useful to start a fire with sticks.
What three ways can friction be useful?
friction is useful for: you to walk It is needed for braking Can be used to produce heat
When is high friction useful?
High friction is useful for lots of things, like a goalkeeper's glove. The more friction there is between the glove and the ball, the easier it is to get a hold of it.
Why is friction useful?
friction is useful because without it we wouldn't be able to walk or do anything for that matter. friction lets us grip onto things with the help of gravity
How can friction be un- useful?
In any part that you want to keep moving, like a spinning wheel, friction is just a nuisance.
Describe 3 examples where low friction is not useful?
Friction is very useful but it has its own disadvantages. Friction causes wear and tear. Friction spoils the soles of our shoes. friction reduces speed This is all wrong some not useful types of friction are are when airplanes fly the friction causes heat that materials that will withstand which are costly.
Does brakes on a bicycle have a lot of friction or not much and is it useful or not useful?
Brakes are meant to have a lot of friction and it's useful.
Why is friction un-useful in sports?
Friction is sometimes not useful as when a player drives forward in a wet condition the ball slows down due to the friction so it is harder to control and difficult to get a shot away. Also a player can lose momentum during fast strides or slip in wet conditions. The ball will slow down because of the friction with the grass so it is easier for the goalkeeper to save it.

Is friction useful with computers?
No Friction Runes Computers
When can friction not be useful in a boat?
the friction from pushing the hull through the water is not useful as long as you're travelling.
What three ways can friction be useful?
friction is useful for: you to walk It is needed for braking Can be used to produce heat
When is a high friction useful?
It can be useful when a ball is catching
Why are tyres useful friction?
how does friction help car tyres?
When is high friction useful?
High friction is useful for lots of things, like a goalkeeper's glove. The more friction there is between the glove and the ball, the easier it is to get a hold of it.
