Engineering mechanics is a branch of engineering that focuses on the behavior of physical bodies when subjected to forces or displacements. It combines principles from physics and mathematics to analyze how objects move and interact under various conditions. This field is essential for designing structures, machines, and systems that can withstand loads and perform reliably. The study of engineering mechanics is typically divided into two main areas: statics, which deals with objects at rest, and dynamics, which examines objects in motion. Understanding these concepts helps engineers predict how structures like bridges and buildings will respond to forces, ensuring safety and functionality in their designs.
