A. Objective of the Course

Objectives of introducing this subject at first year level in all the branches
are:


To study about identification of
different types of forces, systematic
evaluation of effect of these forces, behavior of rigid bodies subjected to
various types of forces, at the state of rest or motion of the particles, as
Universe exist due to force only.


To understand the fundamental p
rincipal, concepts and techniques, both
theoretical and experimental, with emphasis on the application of these
to the solution of mechanics based suitable problems in all engineering.


To provide a firm foundation and formwork for more advanced study at
ev
ery higher semester as the subject of Mechanics of Rigid bodies cuts
broadly across all branches of engineering profession.

D. Instructional Method and Pedagogy:


At the start
of course, the course delivery pattern, prerequisite of the
subject will be discussed.


Lectures will be also conducted with the aid of multi
-
media projector,
black board, OHP etc.


Attendance is compulsory in lectures and laboratory which carries a 5%
compo
nent of the overall evaluation.


Minimum two internal exams will be conducted and average of two will
be considered as a part of 15% overall evaluation.


Assignments based on course content will be given to the students at
the end of each unit/topic and will

be evaluated at regular interval. It
carries a weightage of 5%.


Surprise tests will be conducted which carries 5% of the overall
evaluation.


The course includes a laboratory, where students have an opportunity to
build an appreciation for the concepts b
eing taught in lectures.


Minimum 8 experiments shall be there in the laboratory related to
course contents.

Minimum 6 tutorials which includes solution of minimum 5 numerical
under each head.



E. Student Learning Outcomes


On the completion of the course
one should be able to understand:


Students will able to understand the laws of mechanics and their application
to engineering problem.


Student will be able to understand the fundamentals of stress/strain analysis
and be able to apply them with confidence t
o simple structure.


Fundamental related to subject will facilitate students to design structures,
predict failure and understand the physical properties of materials in higher
semester.
