What Are The Advantages And Disadvantages Of Friction?

The force of friction acts in the opposite direction of motion, so friction slows down the motion of moving objects. Forest fires are caused due to the friction between tree branches. A lot of money goes into preventing friction and the usual wear and tear caused by it by using techniques like greasing and oiling.

Disc brake

A disc brake is a type of brake that uses the calipers to squeeze pairs of pads against a disc or a rotor to create friction. This action slows the rotation of a shaft, such as a vehicle axle, either to reduce its rotational speed or to hold it stationary.The energy of motion is converted into waste heat which must be dispersed.. Hydraulically actuated disc brakes are the most commonly
