a) In the initial design the same threads are used to suspend all the walkways. Thus mass of one does not get compiled into another.
Therefore the total mass supported by the thread on the lowest walkway is independent of the mass it is supporting above.
The mass supported the lowest walkway hence will just be M kg.
Similarly the mass supported by the threads in the original design on the highest walkway will also be M kg .
This is not the same in the new design as the threads are not common for all the walkways. Therefore the mass supported by the threads on the highest walkway will also have a compiled mass of the two lower walkways. Thus the mass supported in the new design will be: 2M kg and so it was doomed to collapse.
