8lbs of pressure per square inch is the amount of pressure needed to break bone
??? This is obviously wrong, if it were true your body would collapse on itself. It’s pretty easy to prove wrong too, just get something that weighs about eight pounds and has an end that occupies 1 inch by inch or less area. Rest it on any bone in your body, and tell me if said bone breaks.
Secondly that doesn’t make any sense, as different bones are stronger than others, there couldn’t possibly be one number across the board.
Finally, for any amount of pressure you could break bone if you have a long enough, thin enough bone.[/quote]
It depends on how fast that 8lbs of force is applied. Usually it is not applied very rapidly and there are mechanisms to absorb the force. Bones do vary in strengths and so do individuals.
However, it is surprisingly easy to break some people’s bones. A lot of old people break bones doing ordinary activities like opening a window. Obviously they have weakened bones but even middle aged people can be heading in this direction. And sedentary people with bad diets. Ironically fat people if they have one good thing going for them it is usually strong bones.
But you take a middle aged sedentary skinny guy vs a middle aged weightlifting strongman and a broken hand is very easy.
Especially if wearing rings (puts weird stress on the bones).
I knew a guy with an enormous hand and a bonecrushing grip that felt like he could easily crush your hand. So I gave him a Captn? crush number ONE to close and he couldn?t. Which goes to show that perceived handshake strength does not necessarily mean someone can close a powerful gripper. A very large hand has an advantage in crushing another, smaller hand.
It also implies to me that someone who CAN close a powerful gripper can / should be able to exert a very hard handshake. More likely though with healthy bones is you?ll compress the hand and all the joints will suffer rather than the bone breaking.
Bones are roughly twice as strong as concrete and 1/5th the strength of hard steel. They bend / give more than concrete but not as much as steel. They are pretty amazing structures. DRINK YOUR MILK!
