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.
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!
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.
The forces are divided into a horizontal and a vertical component, so that you do not have to lift the weight in full directly. The disadvantage is that you get more friction, so that part of the advantage is negated.
