• Trickum Middle School student Ayesha Murshed, eliminated on "helicoidal"
The clear quadrangular 400W WT model has a power output of 400W and the helicoidal 1KW WT one will be able to generate 1 KW of power.
The pulleys, D D, are channeled, and receive the cable, a a, which serves as a helicoidal saw.
As shown in the engraving, the pulley, D, moves the tool, and the pulley, E, causes the revolution of the shaft, n, through a helicoidal gearing, F.
His _helicoidal saw_ is, in reality, an endless cable formed by twisting together three steel wires in such a way as to give the spirals quite an elongated pitch.
The most interesting application of the helicoidal saw is in the exploitation of quarries.
Fig. 7, when once in place form a cylindrical surface provided with 48 helicoidal, dentate channels.
The ascending motion, which is controlled by the endless screws, f, and the helicoidal wheels, m, is in this way effected with great regularity.
In this case the production of light is chiefly due to the fact that calorific condensation, caused by the use of the helicoidal coil surrounding the curved wire, prevents loss of heat in this conductor.
The extremity, v, of the axle of the pulley to the right is threaded, and actuates a helicoidal wheel, E, which transmits motion to the wheel, R, through the intermedium of the vertical shaft, F.
