Introduction to Mechanics in Civil Engineering

In this class, we will begin with an understanding of the balance of forces, which is the most important and fundamental aspect of learning mechanics, and further deepen our understanding of stress and strain. After that, select the most important and simplest ``beam'' among civil engineering structures. By learning the mechanics of beams, students will acquire the basics of civil engineering mechanics. As for the content of the class, we will first confirm the important parts of solid mechanics. Next, we will understand the mechanical characteristics of beam support conditions and fulcrum reaction forces, and learn about the bending moment distribution and shear force distribution of simple beams under the action of concentrated loads and uniformly distributed loads.
The way the class progresses is that the first half is devoted to lectures, and the second half is devoted to exercises to help students understand the material.

1. Students will be able to understand the relationship between Newton's three laws and mechanics handled in civil engineering, and will be able to create forces that act on structures and analyze phenomena that lead to destruction.
2. Students will be able to understand the relationship between (external force, internal force, stress) and (displacement, deformation, strain) and apply it to the analysis of one-dimensional force balance problems.
3. Students can analyze the behavior of a simple statically fixed beam and calculate the fulcrum reaction force and cross-sectional force distribution. Furthermore, it is possible to analyze the bending stress and shear network force that occur in the cross section of the member.
4. Students can calculate the centroid position, first moment of area, and second moment of area of a cross section of a simple shape, and apply it to the bending rigidity of structural members.
5. Students will be able to understand Mohr's stress circle and apply it to principal stress calculations.

The evaluation based on the final exam results is 100%, and a total score of 60% or more out of 100 points is considered passing.
