Teaching Method

Outline:

In order to obtain strength and durability that satisfy the design specifications, it is essential to master the selection of materials, dynamic calculations, and design methods for various mechanical elements. In mechanical design drawing, it is required to have a complex understanding of these. Therefore, using manual winch as a theme, the participants will learn mechanical design and drafting techniques centered on strength calculations. Manual winch is a machine that hoists heavy objects by manual force, and is used in all industrial fields, including the civil engineering and construction fields.

Style:

Perform design calculations and drawing plans based on the design specifications given individually. It is important to design and draft while always imagining the shape of the product in your head. As this course is academic credit course, you are required to submit design calculation sheets and scheme drawings periodically as pre- and post-learning.
【60 class hours + 30 self-study hours】

Notice:

Be sure to bring your textbook, design notebook, and graph paper with you every time. Since design calculations are performed using spreadsheet software, it is desirable for those who have a laptop computer to bring it with them.
