1. Loads
1.1. Static Load
1.1.1. Live Loads
1.1.1.1. For Example: A car is a live load against a bridge
1.1.1.2. A load that moves and changes in magnitude
1.1.2. Dead Load
1.1.2.1. The structure itself/ gravity
1.1.2.2. For Example: A chair is a dead load
1.2. Dynamic Load
1.2.1. A load that can change in magnitude when it is applied
1.2.2. For Example: Winds hitting a structure
2. 4 types of strutures
2.1. Solid Structures
2.1.1. A structure that is strong, made of solid construction materials
2.1.2. Example: CN Tower
2.2. Frame Strutures
2.2.1. A structure with different parts being held together
2.2.2. Example: Eiffle Tower
2.3. Shell Structures
2.3.1. A hollow and curved structure
2.3.2. Example: Taj Mahal
2.4. Combination Structures
2.4.1. A structure containing different types of structures
2.4.2. Exmaple: Football Helmet
3. Internal Forces
3.1. Tension
3.1.1. A force that makes a structure stretch by pulling from opposite sides
3.2. Torsion
3.2.1. The twisting or turning of an object
3.3. Compression
3.3.1. A force that squeezes or pushes of opposite directions.
3.4. Shear
3.4.1. A force that bends or goes in different directions.
4. External Forces
4.1. Magnitude
4.1.1. How hard a force hits a structure
4.2. Direction
4.2.1. The way the force hits the structure (push or pull)
4.3. Point of Application
4.3.1. The place on a structure where the force is applied
4.4. Plane of Application
4.4.1. What angle did the force hit the structure
