### 1.0 Introduction To Structure

1. 1. 1.0INTRODUCTION to STRUCTURES
2. 2. Objectives:At the end of the lesson, students will be able to:1.Name types of forces.2.Name types of loads.3.Distinguish characteristics of primary materials in main structural construction.
3. 3. What is forces? Definiton:Any influence that causes an objectto undergo a certain change, either concerning its movement, direction, or geometrical construction.
4. 4. Do youknow the types of forces?
5. 5. Types Of Forces: TENSION FORCE (daya regangan) 1 Tension refers to when a force is applied that pulls outward against the face of a structural element and stretches it (e.g., stretching a rubber band).
6. 6. Types Of Forces: COMPRESSION FORCE (daya mampatan) 2 Compression represents when a force is applied inward against the face of a structural element, thereby shortening it.
7. 7. Types Of Forces: SHEAR FORCE (daya ricihan) 3 Shear is when a force is applied in parallel to the face of a structural element at an angle that is perpendicular to either compression or tension forces.
