Students in this course will learn through experience about challenges in the application of mechanical dynamics, material mechanics, thermodynamics, and fluid mechanics. Students will get first-hand experience with machines, and conduct experiments on forced vibrations, material bending, stress concentration, heat conduction and convection, the conservation of momentum of fluids, and Reynolds, thereby deepening their understanding of mechanical engineering. Specifically, students will conduct experiments on forced vibrations of single and two degree-of-freedom systems, bending deformation and stress concentration of materials, conversion efficiency of thermoelectric generation, properties of the Stirling engine, the conservation of momentum of fluids and Reynolds. Students will perform a comprehensive exercise in class 8 to deepen their understanding of mechanical engineering.
The main aim of this course is, by conducting application experiments in mechanical engineering, to deepen students' understanding of mechanical engineering and improve critical thinking skills, and practical and problem-solving skills. In addition, students will learn data collection, processing, and organization methods, observation methods, and how to write reports through these experiments.
Students will acquire the following skills from taking this course.
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
Forced vibration, Bending of material, Stress concentration, Heat conduction, Heat convection, Momentum conservation of fluid, Reynolds

At orientation in the first class, the instructor will explain the frame of mind and suggestions for students' experiments, as well as composition guidelines for experiment reports. In class 2 and 5, students will be divided into 2 groups, and exercises will be carried out relating to experiments to be conducted in this course. In class 3 and 4, and class 6 and 7, students will be divided into 4 groups to work on an experiment respectively. Reports must be submitted by the deadline. In addition, students are required to carefully read the experiment manual in advance to ensure experiments are run safely and smoothly.
