Answer 2

➡Machines are made up of moving parts; therefore, they have friction in various locations. The wear and tear caused by the friction is clearly seen in machines that move at high speeds. Friction usually transfers the mechanical energy to heat energy. The main issue for wear and tear is the excess heat caused by friction. That is the reason oil is used as a lubricant to decrease friction. Example is brake pads. This happens for all types of vehicles including bikes and motorcycles. The friction from the brake pads slows the rotation of the wheel, making to stop. Whenever you brake, the brake pads undergo minute wear and tear. Overtime, it will add up.✌✌
