school
design & technology resources - construction kits |
| |
| The following design
and technology construction kits have been designed to demonstrate different methods
of transmission as well as the distinction between speed and power. Each model
contains a clearbox motor that has been designed for use in schools. They have
a virtually unbreakable polycarbonate gear case and tough nylon gears. Gear ratios
can be altered to show the effect on speed and power of the model . After the
kits have been constructed, the main component parts (gearbox, drive train, battery
box and switch) can be re-used to make other models. |
