how do you increase the mechanical advantage of a pulley?
group of answer choices

increase the input/effort force

decrease the number of ropes/pulleys

increase the number of ropes/pulleys

make your rope longer

The answer is: Increase the Number of Ropes/Pulleys.

Explanation:

A "pulley" is an object that supports a particular movement such as supporting a force's change in direction (provided that the direction is applied to a cord). This is regarded as a "simple machine" consisting of a wheel on an axle. This helps guide cables or ropes.

This machine is used in order to decrease the amount of time it takes to do work, such as lifting of objects.

Remember that "mechanical advantage" refers to the ratio between the force applied to a machine and the force produced by it. So, when it comes to pulleys, the mechanical advantage increases when the number of ropes are also increased. They are directly proportional. This goes the same way with increasing the number of pulleys. Once you increase the number of pulleys, the mechanical advantage also increases.
