The mechanical advantage doesn't depend on the distance the load moves,
any more than it depends on the color of the paint in the can.
If the pulley is hanging from the ceiling and you pull down, then the ideal MA is 1 .
If the rope is fixed to the ceiling, the pulley rides on it, and the load is hanging
from the pulley, then the ideal MA is 2 .
It only takes half the effort to move an object but twice the distance
we find mechanical advantage of pulley by using principle of lever. according to this moment of effort is equal to moment of moment of load. As in this case effort arm is equal to load arm. so mechanical advantage is equal to one. but we know we can never finish friction between rope used and pulley so mechanical advantage is less than one
Its 1 you need more than 1 to improve mechanical advantage i think it's 2 A single pulley means one axel, making the IMA = 1. A double pulley's IMA would = 2, and so on and so forth.
use calculator
Fixed Pulley!!
The actual mechanical advantage of a pulley system is calculated by dividing the output force by the input force. It is the ratio of the load force being lifted to the force applied to lift it. This value indicates how much the pulley system amplifies the force applied.
The mechanical advantage of the pulley system in this case would be 3. This is calculated by dividing the distance the rope is pulled (6m) by the distance the load is lifted (2m).
You can increase the mechanical advantage of a pulley system by adding more pulleys to the setup. As the number of pulleys increases, the mechanical advantage also increases. This allows you to lift heavier loads with less force.

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 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 input distance of a single fixed pulley is equal to the output distance. The pulley system doesn't provide a mechanical advantage in terms of distance but does change the direction of the force applied.
The simple pulley is the type of pulley that does not have a mechanical advantage.
The kind of pulley has an ideal machanical advantage of 2 is called "Movable Pulley". From, Bryan Hollick

The formula used to calculate mechanical advantage in a pulley system is: Mechanical Advantage Number of supporting ropes or strands.
The mechanical advantage of a pulley system depends on the number of ropes supporting the moving block or load. More ropes mean a higher mechanical advantage.
