Learning about science and engineering from motorised machines

We can add motors to our machines and learn how power or speed can be varied depending on the problem we are trying to solve.

  • Learning about the gearing between the drive shaft and the load by towing a heavy load up a slope (an inclined plane!): here  (And we improved the tow hitch to prevent wheelies and loss of grip (traction).)


Base case with 1:1 gearing between drive and load




Hand crank to help us determine gear ratios on the Gear Racer
