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?

To find the mechanical advantage of a pulley system, you need to divide the output force (load) by the input force (applied force). For example, if the load being lifted by the pulley is 100N and the force applied is 20N, the mechanical advantage would be 100N/20N = 5. This means that the pulley system provides a 5x advantage in lifting the load.

What is the mechanical advantage of a fixed and free pulley?
A fixed pulley has a mechanical advantage of 1, meaning it doesn't provide any mechanical advantage, but it changes the direction of the force. A free pulley also has a mechanical advantage of 1, as it only changes the direction of the force without providing any mechanical advantage.
The type of pully that does not have a mechanical advantage is?
A fixed pulley does not provide a mechanical advantage because it only changes the direction of the force applied, not the amount of force required.
What kind of pulley has an ideal mechanical advantage of 2?
The kind of pulley has an ideal machanical advantage of 2 is called "Movable Pulley". From, Bryan Hollick
What does the mechanical advantage of a pulley depend on?
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.
What is the mechanical advantage 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.

What is the mechanical advantage of systems of pulleys?
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 type of pully that does not have a mechanical advantage is?
A fixed pulley does not provide a mechanical advantage because it only changes the direction of the force applied, not the amount of force required.

What is the mechanical advantage of a movable pully?
for one movable pulley you would get a mechanical advantage of 2
How can we analyaze the mechanical advantage of a pulley system?
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.
Why can't a pulley have a mechanical advantage greater than 1?
The mechanical advantage of a pulley can be greater than 1.The efficiency cannot but that is a different matter.
What is the mechanical advantage of a fixed pulley?
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.
What is the ideal mechanical advantage and the direction of the input and output for a fixed pulley?
The ideal mechanical advantage of a fixed pulley is 1, as it does not provide any mechanical advantage in terms of force. The direction of the input (effort) and output (load) for a fixed pulley is the same, as the pulley simply changes the direction of the force applied.
What is equal to the ideal mechanical advantage of a pulley system?
The ideal mechanical advantage of a pulley system is two times the number of pulleys in the system. This is the amount of force required to get the system moving.
