The death spiral. An Olympic pair figure- skating routine features an element called the death spiral shown in Figure P5.67. In this routine, the male skater swings his female partner in a circle. If the rotation rate is three-fourths a rotation per second, estimate the tension in the arms that the skaters’ grip must withstand when performing this element. Hint: Approximate the female skater as a point mass located at her waist. It may be useful to take measurements directly from Figure P5.67 and scale appropriately.
