Roamer – Discovery at Every Turn

Written by Dave Catlin and illustrated by Malcom Livingstone.  This comprehensive little book covers all the basic mechanisms:

  • Gears
  • Pulleys and Chain Drives
  • Wheel & Axles, and Winches
  • Wheels and Rollers
  • Levers, Cams and Linkages
  • Ramps, Wedges and Screws

Each section defines the mechanism, explains how it works, its advantages and disadvantages and provides examples of  the mechanism in use.  Where relevant some sections reference the history of the device and provide the simple mathematical formula governing its operation.  This comprehensive book has proved useful to students as young as 5 or 6 who grasp the ideas through the illustrations and brought clarity to high schools students and non-specialist teachers.
