Mechanical advantage of block and tackle

Step-by-step explanation:

A block and tackle is characterized by the use of a single continuous rope to transmit a tension force around one or more pulleys to lift or move a load. Its mechanical advantage is the number of parts of the rope that act on the load. ... Thus, the block and tackle reduces the input force by the factor n.
