Answer:
Explanation:
A block and tackle is a combination of pulleys which reduces the amount of force required to lift something. The trade-off is that a longer length of rope is required for a block and tackle to move something the same distance." A system of pulleys working together can form a block and tackle, which multiplies force in addition to changing the force's direction, meaning less force is required to move an object. The degree to which the block and tackle multiplies force is its mechanical advantage.
