**Course Scope****: **

This course is furnished to provide the civil engineering students with the basic skills in mechanics. Such skills are considered as pre-requisites for many other courses in the civil engineering curriculum. Among the main concepts that are covered in this course are vectors, equilibrium of a particle, equilibrium of a rigid body, trusses and frames, shear and moment diagrams, centroids, and moment of inertia.

**Course Goals**:

This course is designed to provide you with a clear and thorough demonstration of the theory and applications of engineering statics. A complete understanding of concepts involved in statics is absolutely critical to successfully becoming an engineer. Materials covered in this course are crucial to just about every subsequent engineering courses you will take, and every one of these courses will build off the knowledge you gain in this course.
