Mechanics is a branch of physical science and the practical application of mechanics. Applied mechanics examines the response of bodies (solids and fluids) or systems of bodies to external forces. The subject Engineering Mechanics provides wide exposure to the basic concepts of physics along with the static and dynamic implementations of these concepts into everyday life.

About the Course

Concepts will be applied in this course from previous courses you have taken in basic mathematics and physics.  The course is divided into two parts, Statics and Dynamics.

Statics involves the visualizations and analysis of static equilibrium problems with an emphasis on real world engineering applications and problem solving.

Dynamics, on the other hand, deals with bodies in motion and the resulting effects of application of forces with an emphasis on real world engineering applications.

It also covers wide range of Problem Sets, Multiple Choice Questions, University Questions, etc which help students to gear up for the Exams.

Suggested Readings

Any X+II level textbook covering Physics-I and Trignometry

The course text is online at http://www.ezed.in and provides additional exercises and problems. Every lecture contains links to the relevant sections in the text. Be sure to read them!

Course Format

The class will consist of video lectures, which are between 8 and 12 minutes in length. These contain 3-4 integrated quiz questions per video. Also at the end of each video the student will get a chance to test his understanding of the concepts through different Quizzes.
