Q2. Rope. To tie a boat in a harbor, how many times must a rope be wound around a bollard (a vertical rough cylindrical post fixed on the ground) so that a man holding one end of the rope can resist a force exerted by the boat 1000 times greater than the man can exert? First guess. Experiments show that the change AS of the force S in a small portion of the rope is proportional to S and to the small angle Ao in Fig. 16. Take the proportionality constant 0.15. The result should surprise you! Small portion of rope Ad S+AS
