gasoline engine

Gasoline engine Gasoline engine and car Gasoline engine – internal combustion engine which is often used for automobiles, aircraft, small mobile vehicles such as lawnmowers or motorcycles, and outboard motors for boats. The most common engine of this type is a four-stroke cycle internal combustion engine that burns gasoline. Burning is initiated by an ignition system that fires a high voltage spark through a spark plug. Car Engines – Explained (video 6:00) – How engines work. What is an internal combustion engine? This video is the perfect introduction into learning about how cars work, starting with the most important part, … Continue reading gasoline engine

Fluid mechanics – the study of the physics of continuous materials which take the shape of their container. Fluids – In a mechanical view, a fluid is a substance that does not support tangential stress; that is why a fluid in rest has the shape of their containing vessel.And fluid in rest have zero shear stress Fluid statics Fluid dynamics Navier–Stokes equations Bernoulli’s principle Buoyancy Viscosity Newtonian Non-Newtonian Archimedes’ principle Pascal’s law Pressure Liquids Surface tension Capillary action Gases Atmosphere Boyle’s law Charles’s law Gay-Lussac’s law Combined gas law Plasma Rheology – the study of materials with both solid and … Continue reading fluid mechanics

— fluid dynamics / fluid mechanics Everything is Fluid Mechanics and Navier-Stokes equations — Chris Rogers, Tufts Center for Engineering Education and Outreach Fluid Mechanics – science of fluids at rest or in motion in aeronautics, chemical, civil, and mechanical engineering, meteorology, naval architecture, and oceanography. Fluid mechanics or fluid dynamics is the study of the macroscopic physical behaviour of fluids . Fluids are specifically liquids and gases though some other materials and systems can be described in a similar way. The solution of a fluid dynamic problem typically involves calculating for various properties of the fluid, such as velocity, … Continue reading fluid mechanics


Gears – Two toothed wheels fit together either directly or through a chain or belt so one wheel will turn the other. Some gears may have a screw or a toothed shaft in place of one of the wheels. A gear may also be a combination of toothed wheels that produces a certain speed (such as a bicycle’s top gear which makes the bike go fast, and the low gear for slow speed.) Mechanical gears in Nature – gear mechanisms previously thought to be solely man-made have an evolutionary precedent. Scientists say this is the “first observation of mechanical gearing … Continue reading gears
