With a simple haul system with a 2:1 TMA, how much rope must be pulled to haul a load 10 feet?

In a simple haul system configured with a 2:1 mechanical advantage (MA), the relationship between the distance a load is moved and the amount of rope that needs to be pulled is fundamental to understanding how mechanical advantage works.

In a 2:1 MA, for every unit of distance the load moves, two units of rope must be pulled. When raising or hauling a load, this means that if you want to lift the load 10 feet, the actual amount of rope that needs to be pulled will be double that distance.

Thus, to achieve a 10-foot movement of the load using a 2:1 system, you would need to pull 20 feet of rope. This ratio makes it easier to lift heavier loads by distributing the effort required over a longer length of rope, which is why the answer is 20 feet. This principle is essential for understanding the mechanics involved in technical rescue scenarios where efficient load movement is critical.
