1. External Forces
1.1. Gravity
1.1.1. Gravity is the force that pulls an object to the ground
1.2. Magnitude
1.2.1. Magnitude is how strong something hits another object.
1.3. Direction
1.3.1. Direction is either a push or pull.
1.4. External is a force coming from the outside of a structure.
1.5. Point of Application
1.5.1. Point of application is where the object gets hit.
1.6. Plane of Application
1.6.1. Plane of application is the angle of impact.
2. Internal Forces
2.1. Tension
2.1.1. Tension is when a object gets stretched apart by 2 opposite forces
2.2. Compression
2.2.1. Compression is when a object gets pushed together by 2 opposite forces
2.3. Internal forces are forces that come from within a object
2.4. Torsion
2.4.1. Torsion is when an object is being twisted.
2.5. Shear
2.5.1. Shear happens when an object is being pushed or pulled from opposite directions, which results in it tearing/ripping apart.
3. Form & Function
3.1. Form
3.1.1. Form is how a object looks like. (CN tower, Empire State Building tall, sleek etc.
3.2. Function
3.2.1. Function is how a object works like a plane flies, and a ships goes in water.
4. Types of Structures
4.1. Solid
4.1.1. A solid object where is is made entirely out of 1 or multiple materials in a block.
4.2. Frame
4.2.1. A frame is group of parts placed/welded all together
4.3. Shell
4.3.1. A shell structure is structures that is hollow inside.
5. Loads
5.1. Dead Load
5.1.1. Dead load is a kind of static load that is caused by the structure alone.
5.2. Loads is a force causing weight on the structure.
5.3. Static Load
5.3.1. Static load is a kind of load that is stationary.
5.4. Dynamic Load
5.4.1. Dynamic load is a kind of load that is unpredictable for example rain, or snow.
