1. Form and Function
1.1. Form
1.1.1. The way that structures are built
1.1.2. Form affects the physical features
1.2. Examples
1.2.1. The Big Ben Form: Tall and Intricate with a clock Function: Tourist attraction, a clock tower
1.2.2. The CN Tower Form: Extremely tall and thin Function: Radio Tower, tourist attraction
1.3. Function
1.3.1. The purpose of the structure
1.3.2. What the structure can do
2. Internal Forces
2.1. Tension
2.1.1. Pulling an object in opposite directions
2.1.2. e.g. Tug of war
2.2. Torsion
2.2.1. Twisting an object in opposite rotational forces
2.2.2. e.g. Wringing a towel
2.3. Compression
2.3.1. Pushing an object in opposite directions
2.3.2. e.g. Chewing gum
2.4. Shear
2.4.1. Two parallel, opposite forces pulling
2.4.2. e.g Cheese strings
3. Types of Structures
3.1. Shell
3.1.1. Hollow but strong
3.1.2. e.g. Rogers Centre
3.2. Solid
3.2.1. Mostly solid

4.1.1.2.3. e.g. A hurricane blowing a house
4.1.1.3. Dead Load
4.1.1.3.1. The structure itself
4.1.1.3.2. e.g. The floors and walls of a house
5. Factors of Forces
