Question
the question to part a is... In terms of w, find the tension in the lower chain. sorry, i know i cut it out.
the answer to part c is NOT w/2. and as you can see, that is not the answer for part a either.

Tension in the lower chain,
T = w
Tension in the upper chain, T'
Each side of the chain has an upwardpull; tension, sayT'
Total upward pull is 2T'
Cosidering the equilibrium of tehlower pulley,
2.T' = T = w
Hence,
T' = w/2
Since, thechain on the right on which the force is exerted isa continuation of the chain on the right side , above the lowerpulley,
F = T' = w/2
