Experiment involving Atmospheric Displacement.

Recommended Posts

To perform this experiment a motor connected to a rotating disc of a solid construction throughout its volume is required. The motor needs to be able to rotate the disc to as higher RPM as possible (within the limitations of resources), this discs diameter being parallel with the ground will serve to better demonstrate this concept.

 

The other two components required are a means to measure force exerted on the underside of the disc in the upward direction, while the second is a means to measure the force exerted on the top side of the disc in the downward direction.

 

It is worth noting that the two measurements of force exerted upward on the underside of the disc and force exerted downward on the top side of the disc may be better done separately.

 

In order to measure these forces the disc must be able to move perpendicular to the ground against a spring used to measure force.

How do you propose to differentiate the dynamic effects, that are inherently present, when you "rotate the disc to as higher RPM as possible", from those "measure(ed) force(s) exerted on the underside of the disc in the upward direction", and the "force(s) exerted on the top side of the disc in the downward direction" ?

To perform this experiment ...

 

 

... you also need to quantify the force that you think will be produced. This is so that the experimenter knowns what sort of spring or other means will be needed to detect the force. It also allows other possible sources of error to be evaluated.

 

There are a lot of systems that use spinning flywheels or gyroscopes. Some of these are precision devices so if there were any such force it is not large. How large do you predict it to be?

Sam you also need something else.

 

Have a close look at a helicopter next time you see one (one on TV will do).

 

The helicopter has a second spinning rotor, usually mounted in the tail.

 

Have you given any consideration to why this is needed?

 

To echo John Cuthber's comment can you tell us the purpose of this experiment?

Given frictional heating of the air by the disc during rotation means this experiment is basically about the movement of hot air. How ironic.
