Of a single pulley wheel, only that it changes the direction of the force ie: from overhead.

On a block and tackle system, 2 or more pulley wheels are used in a certain way to produce mechanical advantage.
The simplest type of block and tackle offers a mechanical advantage of 2
The kind of pulley has an ideal machanical advantage of 2 is called "Movable Pulley". From, Bryan Hollick
The simple pulley is the type of pulley that does not have a mechanical advantage.
A fixed pulley does NOT multiply the effort force or have a mechanical advantage. It only changes the direction of the effort force. A free pulley multiplies the effort by two. this means the free pulley has a mechanical advantage of 2.information from:www.mhscience02.com
The formula to calculate the mechanical advantage of a pulley system is MA 2 number of movable pulleys.
The mechanical advantage of a pulley system is the ratio of the output force to the input force. It is calculated by dividing the load force by the effort force required to lift the load. The mechanical advantage of a pulley system can be greater than 1, making it easier to lift heavy objects.

The mechanical advantage of the pulley system is the inertia and friction of the unbalanced and balanced forces acting on the mechanical advantage which is part of the pulley system....
A single fixed pulley (:
Single fixed pulley
The mechanical advantage of a pulley system is the ratio of the output force to the input force. It is calculated by dividing the load force by the effort force required to lift the load. The mechanical advantage of a pulley system can be greater than 1, making it easier to lift heavy objects.
The formula used to calculate mechanical advantage in a pulley system is: Mechanical Advantage Number of supporting ropes or strands.
A pulley system has a mechanical advantage of 1 when the input force equals the output force, resulting in no mechanical advantage. This occurs when the pulley is stationary and only redirects the force, without increasing or decreasing it.
