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
Hook (Once Upon a Time) memories. Upon recalling what Emma did to him, Hook immediately renews his plot to revive every Dark One and kill Rumplestiltskin. However, after a confrontation with Emma and Regina, Hook has a crisis of conscience and turns on the Dark Ones. Subsequently, Hook sacrifices his life to destroy the Darkness once and for all.
