The Rotor is an amusement park ride where people stand against the inside of a spinning cylinder. Once the cylinder is spinning at a certain speed, the floor drops out of the bottom of the cylinder but the people do not fall out. A conservative low estimate of the coefficient of static between people's clothing and the cylinder wall is 0.40. The radius of the cylinder is 3.6 m. The minimum number of revolutions per minute (rpm) that the cylinder needs to have so that the people do not fall out the bottom is?

A common carnival ride, called a gravitron, is a large cylinder in which people stand against the wall of the ride as it rotates. At a certain point the floor of the cylinder lowers and the people are surprised that they don't slide down.

What is the frequency f in revolutions per minute of the carnival ride when it has reached the minimum speed to "stick" someone to the wall?
A common carnival ride, called a gravitron, is a large cylinder in which people stand against the wall of the ride as it rotates. At a certain point the floor of the cylinder lowers and the people are surprised that they don't slide down. Suppose the radius of the cylinder is r = 13 m, and the friction between the wall and their clothes is μs = 0.64. Consider the tangential speed v of the ride's occupants as the cylinder spins.

An amusement park ride called the Rotor debuted in 1955 in Germany. Passengers stand in the cylindrical drum of the Rotor as it rotates around its axis. Once the Rotor reaches its operating speed, the floor drops but the riders remain pinned against the wall of the cylinder. Suppose the cylinder makes 24.5 rev/min and has a radius of 3.70 m. What is the minimum coefficient of static friction ?sμs between the wall of the cylinder and the backs of the riders?

You are designing an amusement park ride where riders will stand inside a rotating circular cylinder with their backs against the curved wall. After the cylinder reaches full rotation speed, the floor will lower and the riders will remain suspended against the wall by friction. The static friction coefficient is 0.6 a) determine the minimum acceration of a rider under these condition such that friction will successfully keep the rider from falling. b) find the speed at which a rider will just barely remain supported, for a cylinder with a radius 4.2 m
An engineer is creating a new amusement park where the rides drop straight down and then curve onto their backs and slide horizonally.
