WARNING
In order to ensure correct
function
of
the
electric
motor, a small quantity of
grease is added during the
manufacturing process. As
grease can melt at high
temperatures, it may dirty
the motor. However, it can
simply be wiped off with a
piece of kitchen paper or a
napkin. The grease used is
neither toxic nor hazardous.

  • Page 8 Build a crane with a movable pulley Example: in this case, lifting a weight of 10 kilogrammes (symbol kg - or more accurately, 10 kilogramme-force for all you scientists, symbol: kgf), will require a force of 5 kg. It is a simple machine that provides a mechanical ad- vantage by reducing the physical effort of man.

  • Page 23 Technical facts and curiosities 1968 The "bike" without wheels found in homes and gyms around the world is a recent invention. The mastermind behind it was American inventor Keene P. Dimick, who came up with the idea of a stationary bike that could be pedalled even though it didn't have wheels.
  • Page 24 Assemble an ultralight aeroplane Technical and scientific information Aeroplanes can fly because of the presence of air. Air is a gaseous fluid made up of particles—mostly molecules of nitrogen and oxygen. An aeroplane is "suspended" in this fluid by its two wings which generate a force called lift, supporting the aircraft in flight.
  • Page 25 X2 X6 Collar serves to secure the rod of the propeller once you have inserted it into the aeroplane.
  • Page 26 Technical facts and curiosities 1903 American brothers and bicycle makers Orville and Wilbur Wright, after years of study and research, built a motor-driven aeroplane with two propellers (wingspan: 12 metres, length: 6.50 metres and weight: 275 kg). Their first flight lasted 12 seconds, during which time they travelled 36 metres at a height of 3 metres.
  • Page 27 Build a helicopter Technical and scientific information In a helicopter, the main rotor and blades act both as a wing to generate lift (see the Technical and scientific information for Activity 49), and as a propeller to provide thrust or drive. As the main rotor turns, in a clockwise direction, for example, a counter force is generated in an anti-clockwise...
