I was looking at the immovable bar (as an option to hold someone) and there were no details to know if it could be broken. It can support approximately 8,000 pounds without just falling to the ground, and you can do a resistance test of CD 30 to move it up to 10 feet. But could you say, break the rod in half, without exceeding the limit of 8,000 pounds? My friend thinks "yes, you could" and takes only some statistics higher than the usual iron bar. But I think "no", but immovable does not mean unbreakable, and I'm not sure which one. What do you think?
