Question

Many of us have seen the “Wheel of Death” act at a circus or in Las Vegas (see illustrations below). Typically the performers, by moving to shift the net center of mass of the device, get it to achieve a rotation rate, ?, such that a performer in the center of the top ring is in free fall when ? = 90o . Determine the rotation rate they achieve at that condition, as well as the net acceleration felt by the performer in the bottom ring. What would his equivalent weight be at that point? Also, compute the reaction forces at the supports A and B for that case. Each performer weighs 160 lbs. and the rotating “wheel” has a center of mass at the pivot point and weighs 1000 lbs
