Assigned Department Objectives

Learning and Educational Objectives of the “General Engineering” A-6 （核となる専門分野の既存技術を説明でき，社会から要求されている問題や実務上の問題を見出し設定することができる。）

Teaching Method

Outline:

Based on the knowledge of mechanics learned in the physics class in the 1st grade, the foundation for studying specialized subjects related to mechanical engineering (material mechanics, thermodynamics, fluid engineering, mechanical mechanics, etc.) to be learned after the 3rd grade The purpose is to solidify. Specifically, you will learn about statics related to the balance of forces and moments, and dynamics related to the movement of mass points and rigid bodies.

Style:

It will be done by the faculty member alone. Since it is a basic subject, lectures will be the main focus, but exercises will be included during class as appropriate.

Notice:

It is desirable to understand the basics of physics (especially the field of mechanics) and mathematics that were learned in the first grade. Those who are aware of these lacks of understanding are strongly encouraged to thoroughly review and deepen their understanding. The lesson plan may change depending on your level of understanding.
