APPLIED MECHANICS CE 401
Lecture : 3 Year
: 1
Tutorial : 2 Part : II
Course Objective : This course has been
designed to provide basic knowledge of engineering mechanics to the students of
all branches of engineering so that it would be helpful for them to understand
structural engineering stress analysis principles in later courses or to use
basics of mechanics in their branch of engineering. This course shall be
considered as an introduction: common for all engineering faculties of
Tribhuvan University in the first year of undergraduate. Emphasis has been
given to Statics.
