Homework Statement
In the Rotor Ride at the NM State Fair, passengers stand with their
backs to the wall in a giant rotating drum with a radius of 10 feet. The drum
is brought up to a speed of 33 1/3 RPM, and then the floor is lowered, leaving
the passengers suspended above a giant hole in the floor, stuck to the wall by
friction. The friction coefficient for the drum wall/clothing contact surface is
typically s ' 0:3: Is this high enough to keep the passengers from sliding? How
much can the angular speed be lowered before the passengers slide down into
the hole?
Homework Equations
arad=4∏2R/T2
The Attempt at a Solution
I don't see how we are supposed include the friction coefficient if there isn't a place for it in the equation. Perhaps I am not using the correct formula?
