In order to create or build new machines, robots, etc., mechanical engineers must have the following knowledge and abilities
(1) Extensive knowledge of the basic elements that make up a machine
(2) Ability to design machine elements appropriately, taking safety and other factors into consideration
(iii) Ability to accurately communicate design intent to others through correct drawings
In this class, students will learn about the mechanisms and functions of basic machine elements such as screws and shafts, as well as the standards for machine elements, and acquire the ability to make appropriate selections based on the standards.
Students will also learn about mechanical drafting methods in accordance with JIS, and acquire the ability to understand three-dimensional shapes from drawings and accurately draft basic shapes.
Furthermore, students learn about material strength, stress, and safety factor, and study design and drafting for specific elements such as screws.
(Omnibus system / 14 sessions)

The grades for quizzes and exercises will be 40%, and the grades for the final exam will be 60%, all of which will be combined
to give a perfect score of 100%. The passing grade is 60% or more.
If an exercise assignment is not submitted by the due date, the grade for that exercise assignment will be 0%.
If a student fails to take a quiz or final exam, the score for that exam shall be 0%.
If an exercise is not submitted by the due date without a valid reason, it will not be accepted.
If a student fails to take a test without a valid reason, there will generally be no opportunity for a re-test.
If there is a legitimate reason, an absence form must be issued by the Student Affairs Office.
What is the passing score of 60 points?
The student should be able to explain the basic elements and describe the projection method, section method, and dimensioning method in the drawing method. In addition, the level is to be able to design appropriate dimensions and materials based on the loads applied to the machine elements.
