Topics

  • naming solids: cuboid, cylinder, cube
  • the body is a cuboid, the axles and wheels are cylinders, the load is a cube
  • axles fit through fixed mounting holes
  • each wheel attaches at the centre of an axle end; one part per slot
  • a wheel turns about its own centre
  • rolling: wheel angle = distance travelled / wheel radius
  • matching wheel pairs keep the toy level; bigger wheels lift the body
  • flat faces stack, curved faces roll
  • a construction example: real vehicles are not made only of these exact solids
