Course description
This course is introduced the concept of mechanics based on the classes “Mechanics of materials 1”. Firstly, this course deals with torsion of bars. Next, the analysis for deformation by energy method is introduced. Then, the concepts for two-/three-dimensional stress state is introduced. Finally, buckling of column, mechanical characteristics of materials and various problem are studied.
This course provides various exercises for deep understanding.
Purpose of class
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 the concept of design by rule, the analysis for torsion bar, deformation analysis by energy method, and the stress/deformation analysis for two-dimensional stress state.
Goals and objectives
  1. Understanding the equilibrium of force and moment.
  2. Understanding the geometric relation between displacement and strain.
  3. Understanding the method to calculate stress/strain for torsion bar.
  4. Understanding the energy method to calculate deformation.
  5. Understanding the coordinate transformation for two-dimensional stress state.
