Homework Statement

Assuming spring constant for system A (left) is k
Then system B (middle) is k/2 and system C (right) is 2k

How about this system? Thanks for helping.

replace the two springs in parallel with the spring with the equivalent spring constant. Now you have two springs in series.

How about it? Do you have a question? Showing us pretty graphs doesn't tell anyone what you're stuck on. Also, those bold sentences are there for a reason: use them. State the question, give the relevant equations, and show your attempt at a solution, and then maybe I can give you a hint (or someone else can -- I'm a beginning physics student as well, so I make a lot of mistakes!).

Assuming you understand these statements, which describe the effect of adding springs in series or parallel, you can apply them directly to the new system. Hint: Start by replacing the bottom two springs by with an equivalent single spring.

Looks like rock.freak667 beat me too it! :smile:
