For a pulley, when is it that the mechanical advantage is greater than 1 and when is it that it is equal to 1? If a rope was hung over a pulley with unequal weights applied to both ends, the larger weight (77kg) would pull the lesser weight (30kg) upward, and so what would the mechanical advantage there be?
The thing about this question is that if a rope were hung over a pulley and the tension at each point was the same (neglecting the mass of the rope and pulley), then how is it that if both ends of the rope point downward that the mechanical advantage becomes 2 (if there was just that one pulley)? Is the mechanical advantage any different if someone was applying a force to one end of the rope compared to gravity acting alone?
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 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.
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....

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 to calculate the mechanical advantage of a pulley system is MA 2 number of movable pulleys.
for one movable pulley you would get a mechanical advantage of 2
The mechanical advantage of a pulley can be greater than 1.The efficiency cannot but that is a different matter.
To analyze the mechanical advantage of a pulley system, you calculate it by dividing the output force (load) by the input force (applied force). The mechanical advantage of a pulley system is equal to the number of rope sections supporting the load. More rope sections mean a greater mechanical advantage.
A fixed pulley has a mechanical advantage of 1, which means it doesn't provide any mechanical advantage in terms of force. It changes the direction of the force applied without multiplying it.
