1. Engine: The engine is the source of power in the car. It converts the chemical energy of fuel into mechanical energy.
2. Transmission: The transmission is a set of gears that allows the driver to select the appropriate gear ratio for the current driving conditions. The transmission is connected to the engine on one end and the driveshaft on the other.
3. Driveshaft: The driveshaft is a rotating shaft that transmits power from the transmission to the differential.
4. Differential: The differential is a set of gears that allows the wheels on each side of the car to rotate at different speeds. This is necessary when the car is turning, as the inner wheel and outer wheel need to rotate at different speeds.
5. Axle: The axle is a shaft that connects the differential to the wheels. It transmits power from the differential to the wheels and also supports the weight of the car.
6. Wheels: The wheels are the final components in the power transmission system. They are connected to the axle and rotate when the car is in motion.
When the driver presses the gas pedal, the engine starts producing power. This power is then transmitted to the transmission, where the gears rotate to provide the appropriate gear ratio. The driveshaft then transmits this power to the differential, where the gears allow the wheels to rotate at different speeds. Finally, the power is transmitted to the wheels, which rotate and cause the car to move.
