Better my ass, I am an inventor, enterpreneur, what did you do your whole life on my caliber? I don't know napkin calculation, english is not my first language so my expression is not that good. Being an inventor alone is far greater than anything an engineer like you can be, in both technology and financial achievement. Being a great inventor, who can influence the world, change how battlefield is fought, is not even in your dream, loser

What kind of engineer are you? You failed at the basic engineering In order to increase the load, the increased diameter must run parallel continuously to the axis of the rod, e.g. a full rod, not discrete thread like that which is useless because the chain is as strong as its weakest link. Your theory fails, imagine a steel rod with 1m diameter, but has a section with 1mm diameter. From your calculation, that rod is very strong and can not be broken, but actually it can be broken by human easily. The thread is similar to a 1mm rod with many 1m disks attached discretely along its length, the disks are useless in increasing bending load of the rod, even the diameter is huge.
