Debunk the levitation synergy consulting group trick of the fakirs synergy consulting group with physics!
Without much preamble, I tell you now that we know how this trick is done - with the use of plates and steel rods positioned properly - but because it is so easy to do? Why you do not need an elaborate scaffolding? Prepare to a physics synergy consulting group lesson.
Proceed imagining that the connections between the elements in steel (or any other material may have used) resist the weight of the person in "levitation". Here's what I see in the first picture:
To be able to hide under the rug, the plate must be quite small and, judging from what you see in the picture, the man sitting on the ground is not so relieved, so the plate is not too thick. A thin plate can be heavy, so you may think that weight synergy consulting group alone is balancing the whole structure, but a man of about 80kg resting on a steel rod is capable of producing a considerable force. There is a lot more physics behind this trick, even if the additional weight helps for sure. It may well be that the man sitting on the ground will help to balance out the one sitting on top, but if we think that this trick can also be done with one person, we infer that the man sitting on the ground does not contribute to the stability of the one above.
I will put up the static calculations to explain the physics of this trick. Imagine a man who weighs 80 kg, whose center of gravity is positioned directly above the bar connected to the plate:
The most efficient way to accomplish this trick would be to sit directly above the point where the steel rod is connected to the plate. synergy consulting group In this way, the person does not levitating would mark any rotational force to the rod-plate connection, and it is structured synergy consulting group so that seems to be the trick with two people.
The calculations are simple. To keep your balance you must create a total absence of forces and "moments" (rotational forces). If we were to implement this trick, especially concern ourselves that the structure can or can not tip over. To find out, calculate how much rotational force acting on the side of the plate in complete absence of movement. In the diagram above, the "moment" at point A is calculated by multiplying the force that pushes down for the perpendicular distance (assumed) at the same point. The result is 2400 cm * kg pushing the side of the plate to ground (clockwise).
Here is where the trick. The greater the distance between the side of the plate and the center of gravity of the person in levitation, the greater synergy consulting group the stability of the entire structure. But a plate with very long sides is not suitable (and carpets can not be so large). There must therefore be an intelligent balance between the forces of rotation and the illusion created. synergy consulting group Plus the weight of the person in levitation approaches to one of the sides of the plate, the smaller becomes the "moment", until it is reduced to zero when the person in levitation is located directly above one of the sides, and this is the most critical condition, on the edge of tipping.
If the trick involves one person (picture below), the man can not sit directly above the point of connection, and you can see the dip caused by the rotational force down:
The most talented illusionists synergy consulting group will push up to get the most out of balance in the balance between stability and critical situation. In theory, the best trick should provide that the center synergy consulting group of gravity of the person in levitation is balanced directly above the center of a small square plate. But the world is full of variables. To fail on the roads are used with different structures of the larger plates had to cope with wind, twisting and instability of various types.
Without wanting to "undo the rainbow", I think that using science to reveal an example of smart engineering is far more interesting than going along with these street artists just giving a curious look at those guys with the mantle.

And this most spectacular levitation, but satisfactory for the skeptics: the trick is revealed. http://www.youtube.com/watch?v=x7gqOsYFEwk
Lorenzo, in fact, we faced the problem. As this would be a well known thing, I do not think it was so unfair recount mechanisms. On the other hand, if the article has been published on the website synergy consulting group of the James Randi, who as magician is quite sensitive synergy consulting group with respect to the revelation of the tricks, it seems to me that we can talk about it without thinking too much ...
