Question: Look at the illustration of the pulley system at the right to answer the questions. What additional disadvantages might there be to this system compared to a single fixed pulley system?
Reference answer: You have to pull up in this system.  In the single fixed pulley system, you get a directional advantage.

Student answer: It is harder to use this system than to use a single fixed pulley system.

Student answer: You have to pull up and in the other system you will pull down.

Student answer: The system is single movable system but the single fixed is easier to pull down.

Student answer: Pull down.

Student answer: It has direction advantage it can go up and down.

Student answer: In a single fixed gravity creates a directional advantage. But in this one gravity pulls against you when pulling up.

Student answer: You have to pull more ropes and a single fixed requires more effort.

Student answer: You have to use more effort because you pull down.

Student answer: The amount of ropes supporting it.

Student answer: Single fixed pulley system a smaller effort and only one mechanical advantage.

Student answer: Single fixed only has one rope connected to the load.

Student answer: It would make it harder because if you divide 360 by how many supporting ropes a single fixed pulley has which is one then it would be 360 newtons for the effort that is 180 newtons harder to lift the load.

Student answer: There are more materials.

Student answer: You do not have to pull much rope with the single fixed but it is heavier.

Student answer: The other disadvantage to this system is the effort is going up, so gravity is working against you.

Student answer: The disadvantage is distance in this one and in a single fixed it is that the load's weight stays the same the whole time.

Student answer: This system would take longer to set up.

Student answer: Another disadvantage would be you have to pull more rope to get it where you want it to go.

Student answer: The effort is going up which makes it harder.

Student answer: You would have to pull 3 times as much on this than you would a single fixed. Also, it is easier to pull down than up.

Student answer: In a single fixed you have directional advantage, and you pull the rope as far as the load moves, but a single fixed or single movable up has no directional advantage, and you have to pull the rope 3 times as far.

Student answer: You have to pull up. It may give you mechanical advantage, but it does not give you directional advantage so it takes just as much work.

Student answer: Single fixed you can pull down, which does not give you a mechanical advantage. But you do not pull the rope farther than the load.

Student answer: This pulley system gives you a mechanical advantage the single fixed gives directional advantage.

Student answer: Distance.

Student answer: Another disadvantage might be that you cannot lift the load as high as you can in the single fixed because you are using more string.

Student answer: You have to pull twice as much rope to lift the load.

Student answer: A mechanical advantage. A single fixed pulley gives you a directional advantage.

Student answer: Another disadvantage might be the size of the load. 360 newtons is quite a large load to be pulling upward!

Student answer: You have to use less effort.

Student answer: Compared to a single fixed pulley system, you would not have a directional advantage.

Student answer: You do not have a directional advantage.

Student answer: You have to pull up on this pulley system. On the single fixed you get a directional advantage.

Student answer: This system has a directional disadvantage and the single fixed has a mechanical disadvantage.
