Hi I have physics problem which I'm stuck with.(adsbygoogle = window.adsbygoogle || []).push({});

It goes like this.

An amusement park ride consists of a large vertical cylinder that spins around its axis fast enough for any person inside is held up against the wall then the floor drops away. The coefficient of static friction is [itex]\mu_{s}[/itex] and the radius of the cylinder is R.

I'm suppose to show the following: The maximum period of revolution necssary to keep the person from falling is [itex]T = \frac{(4 \pi^{2} R \mu_{s})}{g}^{1/2} [/itex]

I know that in order to understand the situation I first need to draw a force-diagram displaying the forces acting on both the cylinder and the person inside.

Do I add these forces together then?

Any help/hint(s) will be appreciated :-)
