automechanic

An auto mechanic (or car mechanic in British English and motor mechanic in Australian English) is a mechanic with a variety of car makes or either in a specific area or in a specific make of car. In repairing cars, their main role is to diagnose the problem accurately and quickly. They often have to quote prices for their customers before commencing work or after partial disassembly for inspection. The mechanic uses both electronic means of gathering data as well as their senses. Their job may involve the repair of a specific part or the replacement of one or more parts as assemblies.

Basic vehicle maintenance is a fundamental part of a mechanic's work in modern industrialised countries, while in others they are only consulted when a vehicle is already showing signs of malfunction. Preventative maintenance is also a fundamental part of a mechanic's job, but this is not possible in the case of vehicles that are not regularly maintained by a mechanic. One misunderstood aspect of preventative maintenance is scheduled replacement of various parts, which occurs before failure to avoid far more expensive damage. Because this means that parts are replaced before any problem is observed, many vehicle owners will not understand why the expense is necessary.

car steering system

Steering is the term applied to the collection of components, linkages, etc. which will allow a vessel (ship, boat) or vehicle (car, motorcycle, bicycle) to follow the desired course. An exception is the case of rail transport by which rail tracks combined together with railroad switches (and also known as 'points' in British English) provide the steering function.

A starter motor (also starting motor or starter) is an electric motor for rotating an internal-combustion engine so as to initiate the engine's operation under its own power.

How Clutches Work

A clutch is a mechanical device which provides for the transmission of power (and therefore usually motion) from one component (the driving member) to another (the driven member). The opposite component of the clutch is the brake.

Automobile pedal

An automobile may have two to four foot pedals. The arrangement is the same for both right- and left-hand traffic. From left to right:
normally operated by the left foot:
clutch pedal, not in the case of automatic transmission
normally operated by the right foot:
brake pedal, which is sometimes wide and elevated above the car floor
throttle (known as the 'accelerator' or 'gas pedal'), controls fuel and air supply to the automobile's engine. It is usually narrow and close to the car floor allowing the driver's heel to rest on the car floor. It has a fail-safe design in that it automatically returns to the idle position when not depressed by the driver.
Some vehicles have a parking brake pedal instead of a hand brake lever. Pedals can be either 'hanging' from the firewall (bulkhead) or 'standing' on the floor.
Since the right foot is normally used (for the accelerator or brake) there is no foot rest on the right, not even in cars with cruise control. The left foot only has to operate the clutch intermittently (or has no function in an automatic vehicle) so sometimes a foot rest is provided to the left of the pedals. Some drivers practice left-foot braking, however.
Many cars now include pedals with electric adjustment, a modern iteration of a manual adjustment system available sporadically since the 1950s.

first automobile

An automobile, autocar, motor car or car is a wheeled motor vehicle used for transporting passengers, which also carries its own engine or motor. Most definitions of the term specify that automobiles are designed to run primarily on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods.[3]
