RATIONALE : Mechanics of Materials deals with the internal behaviour of variously
loaded solid bodies, such as; shafts, bars, beams, plates, and columns, as
well as structures and machines that are assemblies of these components.
Mechanics of materials focuses primarily on mechanical properties of
materials, analysis of stress, strain and evaluation of deformations. The
subjects like structural analysis, design of structures as well as machines
are based on adequate knowledge and understanding of Mechanics of
Materials. Therefore, it is an important basic subject for Diploma students
in Civil and Mechanical Engineering. AIM : The aim of the subject Mechanics of Materials is to develop background
preparation of students for taking up Engineering subjects like Theory and
Design of Structures, Design of Machines mostly through the followings:
> Describe the Mechanical properties of important Engineering materials
> Determine stresses, strains and deformations in elastic bodies of
different shapes under different loading conditions for engineering
applications.
> Determine load carrying capacity of different types of members..
