what is the mechanism for a car
Answers
Many modern cars use rack and pinion steering mechanisms, where the steering wheel turns the pinion gear; the pinion moves the rack, which is a linear gear that meshes with the pinion, converting circular motion into linear motion along the transverse axis of the car (side to side motion).
Answer:
The fuel you put in your tank is transferred to the fuel pump by means of the fuel lines. This fuel is pressure injected into the engine after the compression stroke of the cycle at which time the spark plug (only gasoline engine) creates the spark which combusts the air-fuel mixture. Due to this combustion a lot of heat is produced and the energy pushes the piston which in turn rotates the crankshaft which rotates he transmission layshaft, mainshaft, propeller shaft (RWD only), differential gears, halfshafts. These rotating halfshafts finally rotate the wheels.
Disclaimer: whatever you don't get is an individual part of the car. Car mechanism is much much more complex and cannot be explained as a whole. There are numerous individual things that happen together.
