Statics defined

Statics is the name given to the branch of mechanics concerned with forces acting on bodies at rest under equilibrium conditions. The study of statics assumes the following independent conditions:

• The bodies in which forces act on are perfectly rigid and immutable as to shape and size under all conditions.
• The sum of all the forces acting on a body at rest has to be zero (i.e., the forces involved balance one another).
• There must be no tendency for the forces to turn the body about any axis.
