What is the use of Propeller Shaft in each and every vehicle and also plz tell me what is the difference between Front Wheel , Rear Wheel and Four Wheel Drive??? Plz explain

On a propeller Plane it carries the propeller that makes the plane fly. On a ship it does the same to make the ship move.
On most motor vehicles of the older type it carries the radiator fan.
வேறு எதாவது உண்டா? Were you thinking of anything else?

a propeller shaft is a shaft that transmits power from the engine to the rear axle, if the engine is not mounted exactly over the rear axle.

Front Wheel Drive
-Engine drives front wheels only
-Transverse engine configuration
-No driveshaft or propeller shaft
-Traction is improved by having weight of engine and transaxle over drive wheels
-More rear seat room due to flat floor pan, increased trunk space as there is no rear differential
-Decreased vehicle handling as rear tire traction is decreased

Rear Wheel Drive
-Engine drives rear wheels only
-Longitudinal engine configuration
-Driveshaft or Propeller Shaft is required to transmit power and torque from transmission to the rear differential
-Vehicle balance and handling is much improved
-Less interior room in the vehicle
-Traction problems because of lower rear vehicle weight over the drive wheels

Four Wheel Drive
-Engine drives all the four wheels using a transaxle
-Longitudinal engine configuration
-Two differential are present-one at front and one at rear
-Advantages of both front & rear wheel drive
