  2. Work (thermodynamics) - Wikipedia

    en.wikipedia.org/wiki/Work_(thermodynamics)

    Thermodynamic work is one of the principal kinds of process by which a thermodynamic system can interact with and transfer energy to its surroundings. This results in externally measurable macroscopic forces on the system's surroundings, which can cause mechanical work, to lift a weight, for example, [1] or cause changes in electromagnetic, [2] [3] [4] or gravitational [5] variables.

  3. Work (physics) - Wikipedia

    en.wikipedia.org/wiki/Work_(physics)

    The ancient Greek understanding of physics was limited to the statics of simple machines (the balance of forces), and did not include dynamics or the concept of work. During the Renaissance the dynamics of the Mechanical Powers, as the simple machines were called, began to be studied from the standpoint of how far they could lift a load, in addition to the force they could apply, leading ...

  4. Compressor characteristic - Wikipedia

    en.wikipedia.org/wiki/Compressor_characteristic

    Compressor characteristic is a mathematical curve that shows the behaviour of a fluid going through a dynamic compressor.It shows changes in fluid pressure, temperature, entropy, flow rate etc.) with the compressor operating at different speeds.

  5. Young–Laplace equation - Wikipedia

    en.wikipedia.org/wiki/Young–Laplace_equation

    In physics, the Young–Laplace equation (/ l ə ˈ p l ɑː s /) is an algebraic equation that describes the capillary pressure difference sustained across the interface between two static fluids, such as water and air, due to the phenomenon of surface tension or wall tension, although use of the latter is only applicable if assuming that the wall is very thin.

  6. Compression (physics) - Wikipedia

    en.wikipedia.org/wiki/Compression_(physics)

    The compressive forces may also be applied in multiple directions; for example inwards along the edges of a plate or all over the side surface of a cylinder, so as to reduce its area (biaxial compression), or inwards over the entire surface of a body, so as to reduce its volume.

    A type of solid which does not have a definite geometric shape. ampere (A) Often abbreviated as amp. The SI base unit of electric current, defined as one coulomb of electric charge per second. amplifier. Also electronic amplifier or (informally) amp. An electronic device that can increase the power of a signal (a time-varying voltage or current).

  8. Work hardening - Wikipedia

    en.wikipedia.org/wiki/Work_hardening

    Work hardening, also known as strain hardening, is the process by which a material's load-bearing capacity (strength) increases during plastic (permanent) deformation. This characteristic is what sets ductile materials apart from brittle materials. [1] Work hardening may be desirable, undesirable, or inconsequential, depending on the application.

  9. Center of pressure (fluid mechanics) - Wikipedia

    en.wikipedia.org/wiki/Center_of_pressure_(fluid...

    The center of pressure on a symmetric airfoil typically lies close to 25% of the chord length behind the leading edge of the airfoil. (This is called the "quarter-chord point".) For a symmetric airfoil, as angle of attack and lift coefficient change, the center of pressure does not move. [10]
