An amusement park ride (knownvariously as the Rotor, the Turkish Twist andthe Graviton) consists of a large verticalcylinder that is spun about it axis fast enoughsuch that the riders remain pinned against itsinner wall. The floor drops away once thecylinder has attained its full rotational speed.The radius of the cylinder is R and thecoefficient of static friction between a rider andthe wall is us. (i)Show that the minimumFAICTangular speed necessary to keep a rider fromfalling is given by o = √g/us R. (ii) Obtain anumerical value for frequency in revolutionsper minute if R = 4 m and us = 0.4. enclosoTOO07Fig. Ex. 44; The rotor (an amusementpark ride) (For reference only)
