A uniform rod of mass 200 g and length 100 cm is free to rotate in a horizontal plane around a fixed vertical axis through its center, perpendicular to its length. Two small beads, each of mass 20 g, are mounted in grooves along the rod. Initially, the two beads are held by catches on opposite sides of the rod’s center, 10 cm from the axis of rotation.

In a popular amusement parkride, a rotating cylinder ofradius 3.00 m is set in rotationat an angular speed of5.00 rad/s, as in Figure P7.73.The floor then drops away,leaving the riders suspendedagainst the wall in a verticalposition. What minimum coefficientof friction between arider’s clothing and the wall isneeded to keep the rider fromslipping? Hint: Recall that themagnitude of the maximum force of static friction is equal tomsn, where n is the normal force—in this case, the force causingthe centripetal acceleration.
