How do you get the mechanical advantage of a pulley?
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?

What are the advantages and disadvantages of using a pulley?
Advantages - a pulley allows you to apply force in any direction, not just the one in which the force is to applied. Multiple pulleys yield a mechanical advantage that can allow the lifting of heavy weights. Disadvantages - the pulley has to be securely anchored to support the mass being acted on, and the rope has to be strong and durable. A wheeled pulley needs to rotate smoothly, and a sliding (e.g. wooden) pulley should not abrade the rope. Also, the more pulleys you use, the more rope you need. You need to consider the strength of the pulley's anchorage. If you try to raise a 40 lb load using a rope over a single pulley hung from the roof with the 2 legs of the rope parallel, the force on the anchorage will be 2 x 40 = 80 lbs.
