| Outline and Purpose of the Course |
Wood is the most important bio-derived material, constituting the last of human beings' three basic needs: "food, clothing, and shelter." To make the best use of this precious forest resource, it is essential to understand the properties inherent in wood and the functions required of it as a material. This course focuses on the physical properties of wood and what you should understand when using it as a material. |
|||
| Course Goals |
・Wood is commonly used as a structural and interior material in buildings and daily necessities such as furniture and fixtures. This course provides an understanding of the background of this common material. ・Some of the topics covered in particular are wood and water, wood strength, wooden buildings, and nondestructive testing of wood. There are many parts relating to experiments and practical training in the advanced grade, and it equips students with the ability to consider experimental results thoroughly. |
