Course Objectives:
This course has been developed to provide the basic knowledge of engineering mechanics to the students of
engineering so that it would be beneficial to understand structural engineering. The knowledge of mechanics can
utilized in wide range of engineering applications using Newton’s laws of motion and mechanical equilibrium of
different force system. This course shall be considered as a basic for all branches of Engineering of Pokhara
University in first year of undergraduate program.
