授業の目的・概要及び達成方法等(Ｅ）

The class code of this course in Google Classroom system is "vemxeyz" in the academic year of 2024 .

1. Class subject
Mechanics of materials is a branch of applied mechanics that deals with the basic behavior of solid bodies subjected to various types of loading. The knowledge of the stress and strain set up within the bodies and resulting deflection is a prerequisite for the structural design of industrial products and infrastructures such as buildings, roads, bridges, and various equipments. In this course, the basic idea of the structural design is provide based on the quantitative evaluation of mechanical stress and strain fields in various structures.

2. Object and summary of class
This course is intended as an introductory course in the mechanics of solids offered to engineering students. It concentrates on developing analysis techniques from principle for a range of practical problems that include simple structures, pressure vessels, beams and shafts.

3. Goal of study
The goal of this course is the acquisition of the basic concept of stress and strain in material s and structures and the quantitative analytical method of stress and strain fields in various structures.
