This document provides an overview of engineering mechanics, which is divided into statics and dynamics. Statics deals with forces acting on bodies at rest, while dynamics looks at forces on moving bodies and is further divided into kinetics (motion due to forces) and kinematics (motion without considering forces). Key concepts discussed include types of forces and systems of forces. Laws of forces such as the parallelogram, triangle, and polygon laws are introduced to determine resultant forces. Other topics covered are Lami's theorem on forces in equilibrium, the definition of moment of force, and the concept of a couple formed by two equal and opposite forces.
