(a) Show that to design a static structure in a rotating frame (such as a space station) one can use the ordinary rules of statics except that one must include the extra "fictitious" centrifugal force.
(b) I wish to place a puck on a rotating horizontal turntable (angular velocity O) and to have it remain at rest on the table, held by the force of static friction (coefficient µ). What is the maximum distance from the axis of rotation at which I can do this? (Argue from the point of view of an observer in the rotating frame.)
