Structures & Forces #1

1. External Forces

1.1. Weather: rain, snow, ice, wind, etc

1.2. People For Example a person jumping on a roof is a dynamic load

1.3. Live load is caused by weight of the object

1.4. Gravity is the force of attraction between objects

1.5. Dead Load is is caused by weight of the structure itself

1.6. New Node

2. Classifying Structures

2.1. Solid Structures An example of a solid structure is an apple

2.2. Frame Structures An example of a frame structure is a ladder

2.3. Shell Structures An example of a shell structure is an igloo

3. Loads

3.1. Dead load

3.1.1. For example a dead load would be the building itself.

3.2. Dynamic load

3.2.1. For example a dynamic load would be the weather

3.3. Live load

3.3.1. For example a live load would be a rider on a bike the rider would be the live load

4. Internal Forces

4.1. Torsion is twisting An example of Torsion is twisting water out of a towel

4.2. Shear is to rip An example of shear is ripping a piece of paper

4.3. Tension is stretching

4.4. Compression is to push or pressure. An example of compression is a person standing on a snowboard

4.4.1. An example of tension is stretching an elastic band

4.5. New Node

5. Form & Function

5.1. Function: What the structures does and the purpose of the structure An example is school

5.2. Form: how it looks An example of Form is the Walt Disney Concert Hall in Los Angeles California

6. Center of Gravity is the balance and how the structure was supported.

7. That is an example for form versus function
