Students will learn most basic issues in the mechanical engineering field through exercises and experiments. The issues are related to mechanics of materials, thermodynamics, mechanical vibration, and fluid mechanics. Students will deepen their understandings of issues learned in the lectures required in the department of mechanical engineering. Topics covered are (1) Tensile deformation and fracture of materials, (2) Thermoelectric power generation and Stirling engine, (3) Free vibration of 1 and 2 degree-of-freedom systems, and (4) Energy conservation law of fluid flow and flow visualization. In addition, students will learn basics of writing reports of experiments.
The primary aim of the course is a better understanding of mechanical engineering issues and improving the ability to set problems, practical skills and problem solving skills. Additionally, through the group work of experiments, students will learn methods to obtain and process data, and the ability to draw conclusions from findings and write technical reports.
By the end of this course, students will acquire the following abilities:
1) Ability to explain fundamental aspects of mechanical engineering that cannot be learned only from lectures.
2) Ability to conduct basic experiments related to mechanical engineering.
3) Methods to obtain and process data.
4) Consideration on experimental results.
5) Basic ability to write technical reports.

|✔ Specialist skills||Intercultural skills||✔ Communication skills||Critical thinking skills||✔ Practical and/or problem-solving skills|
In the first class of orientation, the instructor will explain attitude, precautions for student experiments, and writing procedures for the experiment report. In the second and the fifth class, students are divided into two groups and complete exercises related to the experiments carried out in the course. In the third, fourth, sixth, and seventh class, students are divided into four groups and engage with an experimental topic. The written report must be submitted by a specified date. Students must read the experiment manual before the start of each experiment to ensure safety and smooth running of the experiment.
