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
Skip a Rope Skip a Rope "Skip a Rope' is a 1967 single by Henson Cargill. The single was Cargill's debut release on the country charts and also his most successful single. "Skip a Rope" was Cargill's sole No. 1 on the country charts, spending five weeks at the top and a total of 16 weeks on the chart. "Skip a Rope" crossed over to the Top 40, peaking at No. 25.
