Course Objectives

Students will learn about strength of materials I, bending stress of beams, deflection of beams, torsion, etc. so that they can solve basic problems. We also aim to understand the solution of the statically indeterminate problem in bending a beam so that it can be applied to actual problems. Specifically, the content described in the "Standard Achievement Level Guideline (Good)" in the "Evaluation (Rubric)" below is the basic goal of this subject.

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:

Strength of materials is one of the fundamental subjects of mechanical engineering, and is a necessary academic field in equipment design, etc. Students are not only required to understand material dynamics, but also, after graduation, they will be involved in equipment design, etc., using material mechanics as a tool. Students are not required to memorize for tests, but must understand the information properly so that they can acquire knowledge after graduation.

Style:

Lecture

Notice:

Students should earn a credit of the strength of Materials I. Students are required to submit all reports. Except in cases of unavoidable circumstances, even if there is one report that has not been, the unit will not be certified if you fail to comply with the submission deadline.
