5 pulleys, 2 fixed and 3 movable, are connected by a single cord. What load can an effort of 100N move with this machine. I hope the solution would be in detail for me to analyze.
Next, we hadn't made the experiment but I hope you would directly tell me the answer. Which machine would be likely to have the greatest efficiency?why?
Last, How does the actual mech'l advantage of a simple machine change with the load?
Thank you to the person who answers this. And God Bless you.

1.
You'll have 6 pieces of cord stretched between the moveable and fixed pulleys so 100N on one of them becomes 600 N total. (Draw a diagram)
2.
Errmmm....... Which of what machines?
3.
The mechanical advantage of a simple machine shouldn't change with the load (until you get to the point that something fails structurally ☺)
