Dynamics of the rotor / gravitron

The rotor or gravitron is an amusement ride: the riders are stuck to the wall of a rotating cylinder while the floor is retracted. This animation shows the 3 forces acting on a rider: gravity, friction and normal force. For more physics animations, please visit http://web.ncf.ca/ch865/

What causes the normal force?

@Gaiacarra

The wall causes the normal force.

[vegunited06]

the ride has nothing to do with gravity, more to do with central fugal force.

Frictional force must be large enough to cancel gravity (so the people don't slide downward). This frictional force is proportionnal to the normal force (centripetal force), which is proportionnal to rotating speed...

In science, this device was the method used to calculate how much g-force the human body could take before health problems arose such as fainting, high pulse rate, bleeding nose, breathing diffuculty, less oxygen/blood traveling to the brain etc. This is what allowed for the creation of space craft. Its primary being the space Rocket e.g like the one used for the first moon landing [1969]. ;}

How do we have N (normal force) ?

Is that mean the tank has to push that man or that man has to push the tank first ?

somebody answer me please..

ok. thanks for clearing that up :)
