Through this lesson, students will:
As a result of this activity, students should develop an understanding of:
The London Eye uses two types of cable, wheel cables and backstay cables. Wheel cables include 16 rim rotation cables, and 64 spoke cables, these are similar to bicycle spokes and stretch across the wheel. There are six backstay cables, which are located in the compression foundation. The compression foundation is situated underneath the A - frame legs; it required 2,200 tonnes of concrete and 44 concrete piles - each being 33 metres deep. The tension foundation, holding the backstay cables, used 1,200 tonnes of concrete. The main elements of the hub and spindle were manufactured in cast steel. The spindle was too large to cast as a single piece so instead was produced in eight smaller sections. Two further castings, in the form of great rings, form the main structural element of the hub. The hub is a rolled steel tube forming the spacer that holds them apart. All the casting was carried out by Skoda Steel. Find out more at www.londoneye.com/LearningAndDiscovery.
1. To get a feel for the construction, students may wish to visit Build the London Eye Online to explore the components of the London Eye. There are also lots of other educational resources at www.londoneye.com/LearningAndDiscovery/Education/TeacherResource/OnlineR....
2. Divide students into groups of 2-3 students, providing a set of materials per group.
3. Explain that students must develop a turning pasta wheel (you may wish to require "weights" such as tea bags which can be tied onto the wheel).
4. Students meet and develop a plan for their wheel. They agree on materials they will need, write or draw their plan, and then present their plan to the class. They should consider the stages of construction.
5. Student teams will request of the "project manager" (you!) the quantity of different pasta shapes they want for their design. They will likely come back and ask for different or additional shapes during construction.
Write an essay or a paragraph about the engineering challenges faced during the construction of either the London Eye or the Singapore Flyer.
