SUMMARY
The discussion focuses on determining the mass m1 required for a static equilibrium in a compound pulley system with m2 set at 60 kg. Participants emphasize the importance of analyzing free body diagrams and understanding tension forces in the system. The relationship between the movements of the masses is crucial; if one mass moves, the other will move in a predictable manner, allowing for the calculation of the necessary tension to maintain balance. The key takeaway is that in static conditions, the lengths of the rope segments remain constant.

If it is static (no motion) then the lengths will not be changing. Look to free body diagrams and tensions instead.

Hello hus, welcome to PF 
The change in length thingy is a good hint, though. But perhaps a little differently: If one of the two moves a little, does the other move just as much, half as much, or twice as much ? From that you can deduce the proper tension force to keep balance. And balance means no change of lengths allright.
