Question

“Rotor” is a ride found in many amusement parks that consists of a hollow cylindrical room (roughly 8 ft in radius) that rotates around a central vertical axis. Riders enter the room and stand against the canvas-covered wall. The room begins to rotate, and when a certain speed is reached, the floor of the room drops away, revealing a deep pit. The riders do not fall, though: they are supported by a static friction force exerted by the persons contact interaction with wall. Estimate the rate at which the room should rotate (in revolutions per minute) to safely pin the riders to the wall. (You may have to make some estimates.)

Perhaps T or TR can help you. They seem to be taking the same course.
