Hi to all of you and welcome to the Forum.
No. 24 seems to have stumped a lot of people, including me at first. Below I'll detail it with out giving the exact answer.
Okay you have 2 lots of sticks on pedestals, what do you think you should do with them.
There is 4 pulleys and on that whole wall there is a diagram which you should follow. It starts on the right and goes to the left. What else can be construed as starting on the right and going to the left? Then the diagram does a big loop and returns to the right. Hint do not pull the fourth pulley twice. Good luck
