What is the mechanical advantage of a gun tackle?

• A. 1:01
• B. 2:01
• C. 3:01
• D. 4:01

Answer: (B)

The mechanical advantage of a gun tackle is 2:1, which means that for every two units of distance that the line is pulled, the load is lifted one unit. This design allows you to apply a smaller force over a longer distance to lift a heavier load, effectively halving the effort required to lift it. In a gun tackle, the arrangement consists of two pulleys, one fixed and one movable. The movable pulley shares the load between the two sections of the line, thus doubling the distance the line must travel compared to the height gained by the load. This setup exemplifies the principle of mechanical advantage in pulley systems, making it easier to lift heavy weights by distributing the weight and effort more efficiently.
