approx. you have to use the force of 5.2 to break a pencil
usually a lot of pressure but it depends on the bone. Example: It takes 12-16 pounds of pressure to break a knee.
It is not so much as how much pressure as where the pressure is applied. If you keep the egg upright and try to apply pressure at the top and bottom, the egg won't break as easily as much as when you apply it in the middle. The shape of the egg gives greater tensile strength to the ends but the middle is comparitively fragile.
Look on Mythbusters. They have a whole episode about duct tape.
you cant measure a pencil in milliliters. how about grams?
pressure=force/area so force is directive propotional to pressure. how much force a karate player will put on that much pressure will apply on that pile of tile. as from the formula we get that pressure is inversely propotional to area so if the area will less then the pressure will be more and by this way the karate player brokes the piles of tiles.

Your question is a bit too broad, because it depends on what bone it is. That's not much of an answer, but if it helps any, I know that if you bend your elbow the way opposite that it is suppose to bend, it only takes 5 pounds of pressure to break it.
You can't break it actually because it is not bone.
"depends on thee bone. Copperhead_51 " That's wrong. As long as there would be no gas in something, the thing cannot break under any kind of pressure (unless you have pressure equivalent to a sun or blackhole). At some pressure, chemicals can start to break down, but your bones would still not break.
It all depends... you could fall the wrong way and break a leg ... or you could be stupid and add too much pressure and break it.
No. It can get sore or feel cramped depending on how you hold your pen/pencil.
very little
40 pounds
50 psi
the amount of pressure created when you face plant on concrete
The human arm's weight depends on the age of the human. Children's arms tend to way significantly less than adult's.
75 pounds of succinct concentrated opposing downward pressure will break almost any human bone
