Chapter 8, Problem 101P
The uniform bar AB is supported by a rope that passes over a frictionless pulley at C and a fixed peg at D. If the coefficient of static friction between the rope and the peg is, μD = 0.3, determine the smallest distance x from the end bar at which a 20-N force may be placed and not cause the bar to move.
