The 5-kg cylinder is suspended from two equal-length cords. The end of each cord is attached to a ring of negligible mass that passes along a horizontal shaft. If the coefficient of static friction between each ring and the shaft is μs = 0.5, determine the greatest distance d by which the rings can be separated and still support the cylinder.
