Question: For balance, a tightrope walker uses a thin rod 8 m long and bowed in a circular arc shape. At each end of the rod

For balance, a tightrope walker uses a thin rod 8 m long and bowed in a circular arc shape. At each end of the rod is a lead mass of 20 kg. The tightrope walker whose mass is 58 kg and whose center of gravity is 0.90 m above the rope, holds the rod tightly at its center 0.65 m above the rope. What should the radius of curvature of the arc of the rod be so that he will be in stable equilibrium as he slowly makes his way across the rope? Neglect the mass of the rod.
