From PAP802 lecture notes qn:
In a popular amusement park ride, a rotating cylinder of radius 3.0m is set in rotation at an angular speed of 5 rad/s as shown in the Figure. The floor then drops away, leaving the riders suspended against the wall in vertical position. What minimum coefficient of friction between the rider's clothing and the wall is needed to keep the rider from slipping?
What kind of sadistic ride is this!
