Four problem-solving activities on the theme of track cycling.
With the Olympics being held in London in 2012 it seemed appropriate to make some TI-Nspire documents based around sport. Since I have some experience of competitive cycling I choose this as a topic. This file was produced after I asked myself ?where's the maths in that??
The TI-Nspire document is split into 4 different activities.
Are all cycle frames the same? Use TI-Nspire to make measurements of images of cycles gathered from the web and to compare angles and ratios of lengths.
Are all cycle tracks the same? Compare the features of 25 tracks around the world using data provided. Then add more data to reach more reliable conclusions.
Activity 3 ? Track Dimensions
The lengths of the straights and the radii of the ends of cycle tracks vary. Build a model track so that it has a particular overall length.
Activity 4 ? A Fermi Problem on gear ratios
How many times do a bike?s pedals rotate during one lap of a cycle track?
