Friction has advantage and disadvantage, In that case friction causes wear and tear. there are two activity to prove friction causes wear and tear. 1)some years back in a flight the nose landing gear failed. it turned sidewards, so when landing due to friction it caused fire and also the metal parts in the wheel was disappeared and also the the rubber tube was gone. so, this activity proves us friction causes wear and tear 2)when the car is travelling 100kmph and when the driver put a sudden brake the car stops after a few seconds but if we see the tires it will not be as same as before the driver puts a brake it smooth and it will not have the threads in the tire. The threads in the car are damaged so, this activity also proves that friction causes wear and tear.
Friction is the main force that is responsible for the wear and tear of machinery, this is why mechanicalæparts are sometimesæoiled, to minimize the friction.
wear and tear the machine parts
When you fall and friction causes you to scrape or tear yourself. At least it stops you, painfully.
The two ways that friction is harmful is that it causes wear and tear of the parts and there is also causes abrasion on surfaces. However, frictions is also useful in various ways like braking when riding a bike and so on.In elevator systems, it is harmful to motor and machine bearings, causes wear. on elevator rails that elevator rides on ,the guide shoes wear and need constant lubrication, unless they use more modern roller guides.

wear and tear
Friction is necessary : If there is no friction between any two surfaces in contact, then the present day civilization will be no more- as we cannot even walk properly on the earth. There will be no fabrics and garments, no construction of buildings and no furniture, even no cooking and no vehicles. So friction is necessary. But too much friction causes a heavy loss of energy, wear and tear of machinery. Thus, the efficiency of machines will decrease tremendously. So, it is rightly said that friction is a necessary evil.

Friction has two unpleasant effects: 1) it increases wear and tear, 2) it wastes energy.
