Statics is the study of the effect of forces on rigid bodies, which are in quilibrium. The main task of static analysis is to determine the equilibrium of the forces applied on a body or a mechanical system.
  • Forces and moments
  • Internal reactions and methods of section
  • Forces in a truss
  • Bridges, beams, arches, cables
  • Static and kinetic friction
Forces and moments
The equilibrium conditions of statics state that a body at rest remains at rest if the sum of all forces and moments acting on that body is zero. Determining the forces and moments is the basis for the design and dimensioning of structures and components.

Internal reactions and methods of section
In statics, the internal reactions show the counteraction of forces and moments within a component in response to the action of external forces. Free body diagrams are the main way in which the internal force states are represented in rods, beams and cables.

Static and kinetic friction

Friction occurs in all solid bodies that are in mutual contact and that are moved against each other. The cause of the occurring forces is, among other things, the surface roughness which causes the surfaces to interlock.
