What is the concept of statics?

Statics is the part of physics that studies bodies on which forces and moments act whose resultants are null, so that they remain at rest or in non-accelerated motion.
The object of statics is to determine the resultant force and resultant moment of all the forces acting on a body to establish its equilibrium conditions.
