This depends on which way you are pushing. Your knee is a hinge joint and is made to flex and extend one way only. Pushing the hinge in the other way can be catastrophic and could be broken from upwards of 30 pounds.
4 lbs I’d kicked to the side.
I heard it only takes 15 pounds of pressure (was told this from a 26 time World Champion Armwrestler).
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.
Since it would probably be tempered glass, 100lbs. of pressure.
5 pounds minimum
You can break your knee in many different ways. 1) somebody kicks you badly on your knee 2) You fall on it badly
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.
3000 pounds of pressure they can snap a broom handle in half
You need six pounds of pressure to torque.
depends on the kind of tile & the thickness & obviously the test method Ceramic or Saltillo will break much easier than Porcelain need more info
556 pounds
35-4500 pounds
