## Area of Study :

The main aim of this first course in mechanics is to develop in the engineering student the ability to analyze any problem in a simple and logical manner and to apply to its solution a few, well understood, basic principals. On successful completion of this course the student will be able to: 1- Know and understand vector analysis in two and three dimensions. 2- Apply vector mechanics to solve and analyze static problems. 3- Identify the reaction supports and draw the free body diagram. 4- Solve practical engineering applications in static involving the equilibrium of particles and rigid bodies under general force systems.

## Mechanics 1

Applications on space vectors, Resultant of forces, Moment of a force, Equivalent couples, Equivalent systems, Equations of equilibrium of a rigid body, Types of supports, Equilibrium of plane systems (Trusses and frames), Equilibrium of space systems acting on rigid bodies, The mass center of a system of particles and laminas of different shapes, The mass moment of inertia of system of particles and laminas.

## a. Knowledge and Understanding:
