Pulley "rove to advantage." Diagram 3 shows that now three rope parts support the load "W" which means the tension in the rope is "W/3". Thus, the mechanical advantage is three. By adding a pulley to the fixed block of a gun tackle the direction of the pulling force is reversed though the mechanical advantage remains the same, Diagram 3a. This is an example of the Luff tackle. The mechanical advantage of a pulley system can be analyzed using free body diagrams which balance the tension force in the rope with the force of gravity on the load. In an ideal
Rope-a-dope Rope-a-dope The rope-a-dope is a boxing fighting style commonly associated with Muhammad Ali in his 1974 Rumble in the Jungle match against George Foreman. In many competitive situations, rope-a-dope is used to describe strategies in which one contender lets their opponent fatigue themself by drawing non-injuring offensive actions. This then gives the contender an advantage towards the end of the competition or before, as the opponent becomes tired, allowing the contender to execute devastating offensive maneuvers and thereby win. The rope-a-dope is performed by a boxer assuming a protected stance (in Ali's classic pose, lying against the ropes, which allows
