A gun tackle has a single pulley in both the fixed and moving blocks with 2 rope parts (n) supporting the load (FB) of 100 N. The mechanical advantage is 2, requiring a force of only 50 N to lift the load.
A double tackle has two pulleys in both the fixed and moving blocks with four rope parts (n) supporting the load (FB) of 100 N. The mechanical advantage is 4, requiring a force of only 25 N to lift the load.
