The port hull of a catamaran (top view shown) has cleats at points A, B, and C. A rope having 100N force is to be attached to one of these cleats. If the force is to produce the largest possible counterclockwise moment about point O, determine the cleat to which the rope should be attached and the direction the rope should be pulled (measured positive counterclockwise from the positive x direction). Also, determine the value of MO produced. Assume all cleats, point O, and the rope lie in the same plane.
