4 Statics Statics is the study of rigid bodies that are in equilibrium and concerned with the analysis of loads such as a force or moment/torque acting on a physical body or system, that is, it is in a state where the relative positions of sub-structures do not vary over time or ...

Statics refers to the branch of physics that deals with the equilibrium and configuration of a system without considering its motion or dynamics. It involves analyzing the geometrical fluctuations and roughness of a system at rest. AI generated definition based on: Physica B: Condensed Matter, 2012...

Both forces and torques are considered in the equilibrium of a rigid body, and the force screw equation is established to express the resultant action of a force system in an absolute coordinate system. The unit screw matrix obtained in kinematic analysis can be directly applied in static ...
For a rigid body acted upon by a system of coplanar forces, equilibrium is achieved when: i) the vector sum of the coplanar forces = 0 ii) there is no net turning effect produced by the forces (the sum of clockwise & anti-clockwise moments = 0) Parallel forces acting on a beam Whe...
