Bout 20 pounds of steel bar
I heard it only takes 15 pounds of pressure (was told this from a 26 time World Champion Armwrestler).
it takes about 9 pounds of force to break your arm
It would only take about 30 pounds of pressure per square inch to break a human neck. At 25 pounds of pressure, it causes instant unconsciousness.
Since it would probably be tempered glass, 100lbs. of pressure.
You probably have too twist and do alot of stuff to it, but, it will get swollen up.
Not very much. I have heard 3 pounds, but have no proof of that assertion. I know at least 2 people who broke their own ribs by coughing.
depends on the kind of tile & the thickness & obviously the test method Ceramic or Saltillo will break much easier than Porcelain need more info
It takes about 7 pounds of pressure to break an elbow according to the UFC
The amount of pressure that it takes to break an arm depends on the strength of the arm and the angle in which the pressure is applied. On the average, it takes 120 pounds of pressure.
Depends. It can take up to 250 pounds of pressure I think.
.8 pounds
If you break your kneecap, you will be in immediate pain, and probably won't be able to walk. If this happens, you need to go to a hospital asap and get an xray. If it really is broken,,,it is quite possible that you will need surgery, not always, but quite often that happens. In either case, you will be put in either an immobilizer or a cast for several weeks. When you're allowed to take whichever you have off,,,you will hardly be able to bend your leg and will probably be sent for physical therapy. You will discover that your muscles are really weak after all the time of not using them much. Trust me, breaking your kneecap is NOT what you want to do,,it is a very , very long road back to any sort of normalcy. Remember, the gangsters who offered to "break your kneecap" didn't do that because it was an easy recovery. Most people who break their kneecap, measure their life before their injury , and after their injury.
