This course deals with basic concepts of mechanics of materials, stress, strain, stress-strain relation. Firstly, the concepts
of stress and strain are introduced based on the equilibrium of force/moment and geometrically deformed object, respectively.
Then, the stress-strain relation is introduced. According to these fundamental concepts, this course deals with the equations
and formulae of stress/strain analysis for simple bar members and beams.
This course provides various exercises for deep understanding.

Designing machines and structures are need to ensure safety use based on analyses of stress/deformation of the objects. Mechanics
of materials has a important role for design by rule, and it is necessary technical knowledge for mechanical engineers.
The purpose of this class is understanding a part of the concept of design by rule, the stress/deformation analysis of simple bar members and beams.
