Investiga (CLIL)

1.5-Investiga:

We can improve the velocity of the spinning changing the gear. Also we can change the velocity of the spinning changing the software that manage it. 

Friction wheels:

They are sistems of 2 or plus discs that are in contact with his peripheries. The contact is realized for the pressure originating that the conductive or driving wheel rotate the wheel driven or trailed.

 

Driving wheel: that that transmits movement. (This wheel can be powered manually or by a motor)

Conductive wheel: that that receives the movement of the driving (wheel).

D1: diametre driving wheel

D2: diametre of conductivitat wheel                                  

n1: velocity of driving wheel (velocity of entry) 

n2: velocity of conductive wheel (output speed)

The relationship between the velocities of rotation of the wheels depends of the size (diameter) from the same and it expresses by the equation.

The reason of the gyration wheel is the contrary of the conductive. If more than 2 wheels are used, the sense of the gyration is changing alternivement.
