1. The heat produce in the moving pqrt of machinery due to friction result in wear and tear of the part.
2. Friction cause waste of energy.
3. Tyres of vehicle and soles of shoes wear ot in a few month due to friction.

1- The friction between the parts of vehicle engines produces heat in various sections of engine.Due to this they lose their energy and size up.
2- Due to friction between the paper and drum of photo state machines the drum gives bad results.
3- If the friction is greater between goes of carrum,we cannot play carrum.

is gripping a pipe with a stillson wrench an andvantage or a disadvantage of friction?
Loss of energy. Any way friction is a necessary evil

Advantage-we can write. Disadvantage- hard to move objects
The main disadvantage of friction is that energy is required to overcome friction and that energy is effectively wasted. On the other hand, friction enables motion. If there were no friction, it would be like an extreme case of trying to walk on ice or on a very smooth surface with an oil slick on it. You could not get any traction to start moving or, if already moving, it would be impossible to change the magnitude or direction of motion.
One disadvantage of friction is when you fall over and graze your knees on contact with the ground. One advantage is to put on your brakes and bring your vehicle safely to a stop!
1) In machines the mechanical parts which rub with each other wear out. 2) Due to friction between the sole of the shoe and the floor the sole wears out. 3) Tyres of vehicles wear out because of friction. 4) Energy is wasted in overcoming the force of friction.
Reduced friction, smoother operation, more power delivered. A big disadvantage is that the slot in the yoke wears rapidly due to sliding friction.
one advantage: it keeps things in their place. one disadvantage: it wastes energy when you move things to another place.
An example using a car:Advantage: friction on car tires makes the car stop. Without friction, the car would continue without stopping (e.g. such as mass in space once given a push in one direction)Disadvantage: friction on car tires means more energy is required to propel the car forward = more gas is required for a trip.
In many ways, Friction helps us a lot, like creates grip, keeps car on the track and many, many more stuffs. In the other hands Friction acts as an opposing force and requires extra energy for any body to maintain at a constant motion. Like a car travelling at 80km/h has a quiet a lot of friction between the tires and in return it adds to fuel consumption.
With friction, you aren't able to go SUPER fast (if you like going SUPER fast). Friction slows us down.It depends on the situation. In some cases, yes; in some, no. Take the example of a car. Friction between the moving metal surfaces inside the engine results in wear on the parts. For the brakes, sliding friction between the break disc and the pads is what stops the car.
