This document provides an introduction to applied mechanics. It discusses key topics including statics, dynamics, forces, moments, and equilibrium. Statics deals with bodies at rest under the influence of forces, while dynamics examines forces on moving bodies. Key concepts covered include rigid bodies, physical quantities, types of forces, characteristics of forces, force systems, methods of resolving forces, and laws of forces such as the triangle law and parallelogram law. The document also discusses free body diagrams, equilibrant forces, Lami's theorem, moments of forces, and Varignon's theorem.
