Engineering Mechanics is an essential analytical subject which focuses on forces and their effects on the bodies. It applies the laws of Newtonian physics to determine the parameters as required. This subject is essential in bridging the gap between physical theory and its application to technology.

About the course

The concepts applied in this course are from previous courses taken up in basic mathematics and physics.  The course is mainly 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.
