When choosing a mechanic course, consider course material, classroom equipment, instructor qualifications, and cost. Determine what you want to study and your goals. Look at the course description and reference material, check for prerequisites, and assess the equipment and student-to-equipment ratio. Research the instructor’s credentials and experience, and compare costs. Hands-on practice is essential, and […]

Training can be obtained through technical schools or hands-on education, and certification can be helpful in job applications. A machine mechanic builds and repairs engines at the […]
To become a mechanic superintendent, one needs formal education, work experience, mechanical aptitude, and supervisory skills. Mechanical systems are found in various environments, and a minimum of 10 years of experience is required. Natural mechanical aptitude is helpful, but it takes effort to learn the skills. Improvement of supervisory and management skills is essential. There […]
A bicycle mechanic builds and repairs bicycles, including difficult tasks like tying up a broken wheel, derailleur service, and repairing bent or damaged frames. They assemble new bicycles, provide maintenance and repairs, and may work with racing teams or in design and research. A bicycle mechanic builds new bicycles and repairs used ones. From basic […]
Helicopter mechanics maintain and repair helicopters for armed forces and companies. They undergo formal aviation maintenance and repair training and may need to pass licensing or certification exams. Mechanics are responsible for inspecting, cleaning, repairing, and replacing components of the helicopter. Military mechanics may lead training classes and handle complex repairs. A helicopter mechanic is […]
Classical mechanics, based on Newton’s laws, describes the motion of objects due to mass and forces. It has limitations for extreme conditions. Quantum mechanics and relativity emerged to explain small objects and large/distant objects respectively. Newtonian mechanics is advantageous for everyday use due to less demanding mathematics. Classical mechanics is a field of study that […]
Fluid mechanics studies the behavior of liquids and gases under forces. It has two fields of study: statics and dynamics. Its roots go back to ancient Greeks and Persian philosophers. It has three basic premises: conservation of mass, momentum, and continuum hypothesis. The latter is an approximation used as a computational tool. Fluid mechanics is […]
Jet mechanics maintain and repair jet engines for commercial airlines, government and private companies. They must be certified by the FAA with an airframe and power plant (A&P) license, obtained through a structured program or 18 months of practical experience. They are responsible for keeping planes in perfect flying condition, including inspection and repair of […]
Quantum mechanics (QM) is a mathematical theory that explains the behavior of particles at the atomic and subatomic level. Particles in the microworld can act as waves, and vice versa, leading to Heisenburg’s uncertainty principle. Some scientists disagree with QM, and the challenge is to unify it with Einstein’s general theory of relativity. Julian Barbour […]
Vehicle mechanics perform routine maintenance, inspections, and repairs on cars, trucks, and other vehicles. They check and change oil, rotate tires, and ensure safety features are working properly. They often have technical or vocational training and can rebuild entire engines. A vehicle mechanic performs a number of tasks related to keeping vehicles in good working […]
A laboratory mechanic’s duties vary depending on the company they work for, including optical, dental, medical, and engineering companies. They maintain, repair, and order equipment and may require specialized training or a college degree. Optical mechanics mold lenses, dental mechanics prepare replacement teeth, medical mechanics test body fluids, and engineering mechanics assist senior engineers. The […]
Isaac Newton developed universal principles to explain and predict the motion of objects in the natural world. His three laws of motion describe the interrelationship between force, mass, and acceleration. The laws explain the concept of inertia, the intrinsic nature of force, and the equal and opposite reaction. Newtonian mechanics provides analytical tools to accurately […]
Gas mechanics work on gasoline-powered vehicles, performing maintenance, engine rebuilds, and adjustments. They must be knowledgeable in fuel injection, forced induction systems, and computer diagnostics. Gas mechanics must work on all makes of vehicles and attend periodic training to stay up to date with new technologies. A gas mechanic works exclusively with gasoline-powered vehicles, not […]
Soil mechanics studies the properties of soil as a building material or foundation, including its formation, composition, and density. Engineers must adapt to the variable properties of soil on a site, which can be determined by sampling and analyzing soil profiles. Different soil structures behave differently in response to stress and water flow, and a […]
Radio mechanics repair and maintain radio communications equipment found in various locations, including aircraft, emergency vehicles, and taxis. They use diagnostic tools to locate faulty parts and perform repairs using new components or wiring. Specialized training is required, and mechanics must continue their education to keep up with new advances in radio systems. Some countries, […]
A bus mechanic is responsible for the maintenance of diesel and gas buses used in public transport and schools. They may work for a company or have their own business, and require formal training and education. The job involves routine tasks and larger repairs, and mistakes can have serious consequences. A bus mechanic is usually […]
A mechanic’s lien is a legal process that secures payment for contracted services rendered on a property. It extends to both the structure and the underlying ground, and until the debt is paid, the landowner has no clear title. Originally used by real mechanics, it eventually found its way into the construction world, where it […]
Structural mechanics maintain and repair aircraft hydraulic systems and structural elements, inspecting for wear or damage, and installing replacement parts. They may also install aircraft engines. High school graduates can become a structural mechanic through military service or post-secondary training, including apprenticeships. A structural mechanic is a person who usually works on various forms of […]
HVAC mechanics install and maintain heating, ventilation, and air conditioning systems. They specialize in different types of systems and require technical training and apprenticeships. Licensing exams are usually required, and certification is considered a plus. They work for contractors or can start their own business. Mechanics who work in the complex heating, ventilation, and air […]
Auto body mechanics have different roles, but all skilled mechanics can remove dents, restore a car’s body, and add new paint. Restoration, bodywork, and paint specialists are employed for each task. Mechanics can also restore the interior, install electronics, sound systems, and better engines. An auto body mechanic can have many different job descriptions and […]
