Function of Propeller

Answer 1

The function of anything with the word "propeller" on any vehicle is the object that "propels" the vehicle, or makes it move. A propeller shaft on a car links between your differential and your transfer case or transmission. The engine essentially rotates the gears in your transmission which in turn rotates the prop shaft itself, or the gears in the transfer case, which also rotates the propeller shaft. The shaft then turns the gears in the differential. The gears in the differential then turn you axles, which in turn rotate your wheels, propelling the vehicle. As for an airplane, a propeller forces air in the direction of the rear of the plane thrusting (propelling) the plane forward. Same idea with a boat only it forces water back causing the boat to be propelled forward.
