Calculate the force in each section of chain as the picture shows.

Decide the scenerio that puts the chain under the greatest force and calculate that force.

2. Relevant equations

f1 * L1 = f2 * L2

3. The attempt at a solution

The first question I get but the other I can't figure out for the life of me.. Tips?
