Teaching Method

Outline:

This lecture is a continuation of the 2nd year Basic Structural Mechanics. First, we will learn about concepts such as stress and strain and how to calculate cross-sectional properties such as moment of inertia. In addition, students will learn how to think about and calculate cross-sectional forces for structures that model actual structures such as beams, trusses, and rigid frames. In order to deepen understanding, we plan to conduct exercises during class.

Style:

Classes are basically written on the blackboard. You may need to explain content that is not included in the textbook, so please write down what you have written on the board in your notebook.

Notice:

In class, we explain as many example problems as possible, and practice problems are given as homework as necessary. For examples and homework, please use paper and a pencil and try to understand the contents while thinking enough in your head. Since the amount of calculation will increase, please carefully transform the formula properly so as not to make a mistake.
