- Homework Statement
- The masses of pulleys are negligible. What is the value of force F that keeps the block of weight 40 N in balance?

- Relevant Equations
- This system confuses me a lot. Our teacher just summed up all the tension forces of vertical strings, got 5F = 40, but can we really do that? If tension is the same everywhere, why isn't F = 40? Because all these strings aren't attached to the block itself I think. Could someone please explain how do systems like this actually work?

I used the regular way of solving problems with pulleys. I tried to find the tension forces, which must be the same in the rope, but I get it wrong
