I don't know, have you seen how small the links in those chains are? I don't think something like that would make it to 9-B.
Most of the calculations I've
seen put similar feats in 9-C (I know this last one I put is 9-B, but it talks about multiple links, use only one link and the result will be 9-C; 11.64 * 597 = 6949.08 J). Not to mention that the way he could break the chain is not seen, and it is mentioned that the chain could stop him for a moment, so it would take more than one hit to break the chains.
I have some problems with that calculation.
- It wasn't accepted and the person who evaluated it seems to have some issues with it.
- There is a better calculation that puts the result of that at 9-C (4973.301956602 Joules, I only take into account the plastic layer and do not take into account the glass, due to the following point)
- The fragmentation of glass is not currently accepted, due to its fragility and the fact that it apparently does not absorb energy as other materials do. There is another way to calculate glass shattering, though it requires a new calculation.
Also, both calculations don't work for this feat anyway,
since it happens off-screen and The Rake isn't shown to have completely destroyed the windshield.
