  2. Mechanical engineering - Wikipedia

    en.wikipedia.org/wiki/Mechanical_engineering

    Mechanical engineering is the study of physical machines that may involve force and movement. It is an engineering branch that combines engineering physics and mathematics principles with materials science, to design, analyze, manufacture, and maintain mechanical systems. [ 1 ] It is one of the oldest and broadest of the engineering branches.

    CNC – (CNC)), the automated control of machining tools (drills, boring tools, lathes) by means of a computer. An NC machine alters a blank piece of material (metal, plastic, wood, ceramic, or composite) to meet precise specifications by following programmed instructions and without a manual operator.

    en.wikipedia.org/wiki/Geometric_dimensioning_and...

    Example of true position geometric control defined by basic dimensions and datum features. Geometric dimensioning and tolerancing (GD&T) is a system for defining and communicating engineering tolerances via a symbolic language on engineering drawings and computer-generated 3D models that describes a physical object's nominal geometry and the permissible variation thereof.

  5. Applied mechanics - Wikipedia

    en.wikipedia.org/wiki/Applied_mechanics

    Applied mechanics is the branch of science concerned with the motion of any substance that can be experienced or perceived by humans without the help of instruments. [1] In short, when mechanics concepts surpass being theoretical and are applied and executed, general mechanics becomes applied mechanics. It is this stark difference that makes ...

  6. Maintenance engineering - Wikipedia

    en.wikipedia.org/wiki/Maintenance_engineering

    Maintenance Engineering is the discipline and profession of applying engineering concepts for the optimization of equipment, procedures, and departmental budgets to achieve better maintainability, reliability, and availability of equipment. Maintenance, and hence maintenance engineering, is increasing in importance due to rising amounts of ...

  7. Simple machine - Wikipedia

    en.wikipedia.org/wiki/Simple_machine

    A simple machine is a mechanical device that changes the direction or magnitude of a force. [1] In general, they can be defined as the simplest mechanisms that use mechanical advantage (also called leverage) to multiply force. [2] Usually the term refers to the six classical simple machines that were defined by Renaissance scientists: [3][4][5 ...

  8. Solid mechanics - Wikipedia

    en.wikipedia.org/wiki/Solid_mechanics

    Solid mechanics (also known as mechanics of solids) is the branch of continuum mechanics that studies the behavior of solid materials, especially their motion and deformation under the action of forces, temperature changes, phase changes, and other external or internal agents. Solid mechanics is fundamental for civil, aerospace, nuclear ...
