For a Rope and Pulley System that is a Block and Tackle, is characterized by:

* If the rope does not dissipate or store energy, then its mechanical advantage is the number of parts of the rope that act on the load.- if the anchor knot is at the load ("A", "D", and "E") then the mechanical advantage will be odd. (1:1, 3:1, 5:1, etc.)- if the anchor knot is at the anchor ("B", "C") then the mechanical advantage will be even. (2:1, 4:1, 6:1, etc.)- to calculate haul distance, multiply the distance need to go by the mechanical advantage. (3:1 ratio, 20 ft to haul, multiply 3 x 20 ft to get a total of 60ft)
