Chapter 8, Problem 8-18(choose chapter or problem)
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 rings can be separated by the greatest distance d = 400 mm and still support the cylinder, determine the coefficient of static friction between each ring and the shaft.
