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.

Teaching Methods

Theoretical discussions of each new concept with limited number of examples are provided by the instructor. This type of teaching is provided every 3 hours per week. Teaching assistant provides a 1 hours per week in which he/she conducts discussions type of teaching to solve pre-assigned homework problems. The instructor or his assistant may use the traditional chuck board teaching tool or transparency projector tool.

Assessment of Learning

The final grade will be assigned as follows:
          Assignments and Quizzes:                     15 %

          Mid-Term Examination:                        25 %
          Final Examination:                                 60 %
