Konsep-konsep dasar mekanika

Konsep-konsep dan definisi-definisi yang tepat merupakan landasan untuk mempelajari mekanika, dan harus dimengerti terlebih dahulu.

Ruang adalah daerah geometri yang ditempati oleh benda yang posisinya digambarkan oleh pengukuran linear dan anguler relatif terhadap sistem koordinat. Untuk persoalan tiga dimensi, niang takes three coordinates are free, as for the question of two dimensions required only two coordinates only.
Waktu adalah ukuran peristiwa yang berurutan dan merupakan besaran dasar dalam dinamika. Waktu tidak dapat dimasukkan langsung dalam analisis persoalan statika.
Massa adalah ukuran kelembaman benda, yang merupakan penghambat terhadap perubahan kecepatan. Mass is tjal important to the matter because the mass is also a statics properties of any objects that have other objects with the styles of attraction.

Style is the action of an object against another object. A style tends to move the se-fruit-body according to the directions of work. The action of a style characterized by the magnitude, direction of work, and it works. Style is the vector quantity

Particle. An object that is called dimensmya can be ignored. In the mathematical sense, a particle is that these dimensions close to zero so that it can dianali-sis as a mass point. Often an element is selected as the differential particle of an object. In addition to that, If the dimensions of an object does not correspond to the image of his position or action is applied styles, These objects can be treated as particles.
Rigid body. An object is considered a relative movement between the Overdrive if negligible parts direct. As an example, calculation of traction (tension) wiring supporting pillar of the car transporting penderek load is basically not affected by re-gangan (deformation) in that small on structural members of these poles. To go-ness of this, determination of external working on that we can treat it as rigid body. Statics are primarily discussing the calculation. external acting on a rigid body is in equilibrium conditions. To determine the voltage and strain in, characteristics of deformation of the material (material pole must be analyzed. This type of analysis included in the lesson of mechanics that objects can change form, learned after statics.
