Statics is the branch of physics concerned with the analysis of loads (force, torque/moment) on physical systems in static equilibrium, that is, in a state where the relative positions of subsystems don't vary over time, or where components and structures are at rest under the action of external forces of equilibrium. In other words it's how forces are transmitted through the members in an object such as a crane from where it's applied on the object, the hanging end, to where it's supported from… (More on Statics)
