Sounds are everywhere, and you have two cool parts on your body that let you hear them all: your ears! Your ears are in charge of collecting sounds, processing them, and sending sound signals to your brain.
Still the classic, rear drive was basically the only drivetrain system for many years. A longitudinally mounted engine, with the transmission bolted directly to it, sends power via a driveshaft to a differential unit at the rear axle. The differential turns the power 90Â° and sends it to the rear wheels.
Actually the charging mechanism in an automobile is the alternator, and it works whether the wheels are moving or not. The alternator is one of the parts in the engine compartment that have a drive belt. These are the belts that turn the cooling fan for most cars, and for that reason the belts are commonly known as fan belts.
