Topic Overview
Core introduction, context, and relevance of Statics.
Statics is a branch of mechanics that studies forces on objects at rest. It tells us when an object or structure does not move or change shape. Engineers use statics to design safe bridges, buildings, and machines.
By learning statics, you learn how to balance forces and moments so structures stay stable.
