Question

I have two machines a pulley and a block and tackle
I have 5 weights weighing 1 gram 2 grams 3 grams 4 grams and 5 grams. On each machine I raise the weight 5 cm.
pulley
1 gram = 1 newtons of downward force
2 gram = 2 newtons of downward force
3g = 3n
4g = 4n
5g = 5n
Block and tackle
1g = .5n
2g = 1n
3g = 1.5n
4g = 2n
5g = 2.5n
I will post my questions next

Answer 1

1. How did the resistance force relate to the effort force for the fixed pulley alone? How did the resistance force relate to the effort force when you added a movable pulley to the fixed pulley? How does the mechanical advantage compare with the slope of the line for each pulley? Explain using your data.

Answer 2

2. How did the work output relate to the work input for the pulleys? Explain using your data.

Answer 3

3. briefly summarize how the pulleys worked with respect to changes in effort force and effort distance compared with resistance force and resistance distance. What are the advantages of using pulleys? What do you think would happen to the mechanical advantage if you added a third movable pulley?
