There are only three major principles on which our working model generally works:

Power Transmission through Chain Drive: Chain drive is a way of transmitting mechanical power from one place to another. It is often used to convey power to the wheels of a vehicle, particularly bicycles and motorcycles. It is also used in a wide variety of machines besides vehicles. Most often, the power is conveyed by a roller chain, known as the drive chain or transmission chain, passing over a sprocket gear, with the teeth of the gear meshing with the holes in the links of the chain. The gear is turned, and this pulls the chain putting mechanical force into the system.

Bernoulli’s principle: In fluid dynamics, Bernoulli’s principle states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid’s potential energy. The principle is named after Daniel Bernoulli who published it in his book Hydrodynamica in 1738. Bernoulli’s principle can be applied to various types of fluid flow, resulting in various forms of Bernoulli’s equation; there are different forms of Bernoulli’s equation for different types of flow. The simple form of Bernoulli’s equation is valid for incompressible flows (e.g. most liquid flows and gases moving at low Mach number). More advanced forms may be applied to compressible flows at higher Mach numbers (see the derivations of the Bernoulli equation).
