Mechanics
the mechanics are a subsection of physics and are concerned with the movement of bodies and the effect of forces.
Basic Law of the mechanics became from Galileo Galilei (1564 - 1642) and Isaac Newton (1643 - 1727) develops.In 19. One accepted century that all physical features have their origin in mechanical procedures. Therefore this range is often also called today the “classical mechanics” or “Newton's mechanics”. It is physics itself moving objects thatand describes everyday kind for example the free case of objects, planetary motions or movements of rigid bodies (z. B. Gyroscope).
One knows today that in many areas of physics own regularities exist and the mechanics in the formulation of Newton onlyan approximation represents, the z. B. for relativistic systems to be adapted must. The mechanics with its terms, like mass and Kraft , nevertheless remain a basis of physics and above all all technical applications.
After its investigation article one can do thoseMechanics gases
- a finer organization divide arise
- as a result of consideration
- of the which are the basis
theoretical concepts in mechanics of the firm bodies mechanics of the liquids mechanics for that:
- Classical mechanics
- statics (the Kraftverteilung in a resting system) kinetics
- describes (describes the movement ofBodies without consideration of the working forces)
- dynamics (describes the behavior and the forces in moved bodies)
- technical mechanics
- statics
- strength theory (Elastostatik)
- dynamics
- machine dynamics
- continuum mechanics
- soil mechanics (describes deformations and tensions in continuums (z. B. Semi-infinite spaces) with material laws, those the materialMaterial laws of soils) material science
- ( compile mathematical material laws, material material laws the if possible close to come are and in complex computations with reasonable cost of computation to be still usable be supposed) approximates
- statistic mechanics (the behavior of Vielteilchensystemen , z describes. B. in thermodynamics)
- Special relativity theory (for systems, whose speed is close of the speed of light)
- general relativity theory
- quantum mechanics (for systems within the atomic range)
- to science of flow (fluid mechanics, fluid mechanics)
