You are the safety officer for an amusement park ride in which passengers stand inside a 3.0 m tall, 5.0 m diameter hollow steel cylinder with their backs against the wall. The cylinder begins to rotate about a vertical axis. Then the floor drops. When this happens the passengers should “stick” to the wall. Clothing has a static coefficient of friction with steel between 0.60 and 1.0 and a kinetic coefficient of friction between 0.40 and 0.70. What would you recommend for the minimum rotation frequency in rpm so that the ride is safe?

Answer #1

Solution: -

use the concept of static friction the sufficient static friction b / w the cloths ofo passengers and the wall of t he cylinder is required to suppoprt to gravitational force of the passenger the minimum angular velocity corresponds to the maximum frictional force.

The free body diagram of the passenger is given as follows.

Here, mg is the gravitational force acting on the poassenger n is the normal reaction for -ve acting on the passenger by the wall of the cylinder and fs is the static frictional force.

In an amusement park ride passengers stand inside a hollow cylinder of 2.12 meter radius. The cylinder is then spun and the floor of the cylinder is dropped away as the passengers stick to the wall. If the coefficient of static friction between the passengers and the wall is 0.551, with what angular velocity (rpm) does the cylinder have to be rotating so the passengers don’t slide down the wall?

On a trip to the amusement park, Mikey decides to ride The Rotor, a spinning ride that is shaped like a long cone.You stand pressed against the inner wall, and the ride begins to spin. Once it reaches a certain speed, the floor drops, but the force of the spinning keeps you from falling out. For our example, The Rotor is 10 meters tall, has a bottom diameter of 7 m (where the passengers stand), and the walls are set...

The Spinny-Spin ride at the fair is a giant rotating cylinder with people on the inside. Once it spins up to speed, the floor drops out from under the people, leaving them pinned against the wall. The inside surface of the cylinder is coated with rubber which gives it a coefficient of static friction with clothing of 0.85. If the cylinder has a diameter of 3.5-m, what is the lowest number of rotations per minute that will keep the riders...
