Moving pulleys provide mechanical advantage which is the factor on which the input force or effort is multiplied. The mechanical advantage would be 1 because the force required to life the mass of an object becomes 1 2 the original weight of the object. There is no mechanical advantage to using a single pulley. A lever or pulley connected to a shaft.

On the other hand if a pulley is moving its theoretical mechanical advantage is two. How does a single fixed pulley differ from a single. Mechanical advantage which is correlated to the usefulness of a machine refers to the proportion of force output to force input. Which means that force required to move the object is equal to the weight of the object.
