1. Type of Structure
1.1. Combination Structure
1.1.1. Frame
1.1.1.1. Beams connecting from the centre
1.1.1.2. Beams on the outer side of the Eye
1.1.2. Shell
1.1.2.1. The pods are hollow
2. Form and Function
2.1. Form
2.1.1. A diameter of 120 meters
2.1.2. Circular
2.1.3. Lights up at night
2.1.4. Made of steel
2.1.5. 135 meters tall
2.2. Function
2.2.1. Tourist attraction
2.2.2. Looks over the London City
3. The Forces
3.1. Internal Forces
3.1.1. Torsion
3.1.1.1. The Centre
3.1.1.2. The centre spins
3.1.2. Compression
3.1.2.1. Once a passenger sits weight is pushed down
3.1.2.2. The inside of a pod
3.1.2.3. When the centre is pushing the pods higher
3.1.3. Tension
3.1.3.1. When there is a load in the pods, it gets pulled from the structure
3.2. External Forces
3.2.1. Live Load
3.2.1.1. People riding in the pod
3.2.1.2. Too much mass in one pod may resolve in structural failure
3.2.2. Dynamic Load
3.2.2.1. Any weather changes
3.2.2.2. Wind, rain, snow etc.
3.2.3. Dead Load
3.2.3.1. The pod, the beams connecting the pods to the centre
3.3. How it can withstand these forces
3.3.1. Steel beams
3.3.2. Closely weaved to make it stronger
3.3.3. Two thick beams creating an upside-down V helps support the structure
3.3.4. The base supports the centre of gravity because it's wide and large
