Course description and aims

This course gives an overview of mechanics, from Newtonian, Lagrangian, Hamiltonian formulation, and via Mechanics of Materials, to Continuum Mechanics. Students should acquire accomplishments to intuitively grasp force balance of multi-body systems and internal stress and strain states in materials although they are usually not visible. By solving each assignment one by one, the students can understand the general principles in mechanics, which is the fundamentals for modern scientists and engineers, and also brings the students touch of learning in their life.

Student learning outcomes

By the end of this course, students will be able to
1) intuitively grasp force balance of multi-body systems
2) intuitively understand internal stress and strain states in materials
3) propose mechanical model to express phenomena in our real world
4) treat mathematical formulation in vector and tensor


Newtonian Mechanics, D'Alembert Principle, Free Body Diagram, Lagrangian, Hamiltonian, Stress Vector, Mohr's Circle, Tension, Compression, Shear, Beam, Stress Tensor, Strain Tensor, Displacement, Constitutive Equation, 2-dimensional Elastic Theory

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

The students are required to download teaching materials in every class and read it before coming to class.
The instructor explains the essential points of each class and gives assignment to the students.
The students should solve the assignments during the class.
The instructor designates one of the students who should explain the solution by using chalk and blackboard.
The instructor comments on it, or makes a correction when the solution is not perfect.
