Why is friction cut down in a hovercraft?
How is friction cut down in a hovercraft? This is done by hovering over the surface Why is friction cut down in a hovercraft? Because the surface of the hovercraft is smooth
How and why is friction cut down in a hovercraft?
Friction is cut down in a hovercraft by the large volume of air that blows out from under the skirt, making the skirt rise above the ground. In essence, the hovercraft is floating on a bubble of air, and has very little friction with respect to the ground.
What is the job for joints?
To allow the body to move around and not be stiff like a cardboard cut out.
How and why friction is cut down in a car engine?
How - with cooling oil Why - because friction causes heat, and overheating is bad for moving parts.
What are the Small balls that help cut down on friction inside machines?
Ball bearings
Why is friction cut down on a dance floor?
Friction on a dancefloor is reduced by the highly polished floor and leather bottomed shoes worn by the dancers
What is used to cut down friction in a car engine?
How- cooling oil why- overheating is bad for the engine parts
What is friction between moving parts of an engine?
Friction is cut down in a car engine for two very important reasons. First, cutting down friction increases horsepower. It takes horsepower to overcome friction; so anything that can be done to cut down friction will increase the horsepower. Second, friction causes heat to be produced. Too much heat is bad, because if the engine gets too hot, then metal is softened and weakened, leading to failure of engine parts. The engine has a cooling system to remove unwanted heat, but too much friction would require a larger and more efficient cooling system to remove the excess heat, which would add expense and weight to the car. Motor oil is used to cut down the friction in the car engine. Also, very close tolerances in production of engine parts helps to cut down friction.
Why is friction an important factor to consider when designing a race car?
Gravity is good. It keeps the cars down on the track, and the fans in their seats. Friction is bad. If there was no friction, then you could cut your engine when you hit 200 and just keep going. But friction robs your kinetic energy, so if you back off your engine, then your car slows down.
Where do racing car drivers not want friction and why?
Down the straights because it can slow their top dpeed down and they need to cut through the air as cleanly as possible.
What can you eat to cut down on body fat?
Lean meats and vegetables.
What is a disc pad chamfer?
slot cut down the center of the pad. it is there to disapate heat and gases caused by the friction of pad to rotor contact
