Students in this course will learn about advanced topics within mechanical engineering through experiment. Students will conduct experiments on the microstructure and mechanical properties of heat-treated steels, the critical speed and balancing of rotation shafts, the vapor compression refrigerating machine, the visualization and velocity measurement of Karman vortex street, the energy release rate and fracture toughness, the active control of vibration, and the principle and characterization of fuel cells.
The main aim of this course is both to deepen students' understanding of mechanical engineering and improve critical thinking skills, practical skills, and problem-solving skills by conducting progressive experiments in mechanical engineering. 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) Skills for explaining developmental aspects of mechanical engineering that cannot be learned just from classroom lectures
2) How to run experiments on advanced topics in mechanical engineering
3) Critical thinking skills, practical skills, and problem-solving skills
Heat treatment, Critical speed, Refrigerating cycle, Karman vortex, Farcture toughness, Active control, Fuel cell

At orientation in the first class, students will be explained about the frame of mind and suggestions for this course, as well as composition guidelines for experiment reports. Then students will be divided into 6 groups, and each research topic will be worked through sequentially. Reports must be submitted by the deadline. In addition, students are required to carefully read the experiment text in advance to ensure experiments are run safely and smoothly.

Experiment text is distributed by the instructor.
Students are required to attend all classes and perform all experiments and to submit all reports. Students will be comprehensively evaluated on the content of experiment reports.
Students are required to have successfully completed Basic Experiments for Mechanical Engineering (MEC.P211.A) and Advanced Experiments for Mechanical Engineering (MEC.P211.A), or have equivalent knowledge.
The number of registering students will be limited because of experimental apparatus and safety reasons.
