Answer:

To lift the load while changing the direction of a lifting power, a single fixed pulley is being used. While there is no mechanical advantage with a single fixed pulley, the effort exerted is greater than that of the load, because you should not have to pull or drive the pulley up and down, it is preferable to use.
