Human bones are strong! For instance, a bone can survive a strike of 10,000 joules of kinetic energy (3,700 foot-pounds of force) as long at the strike is perpendicular to the surface. Additionally, most bones are padded with soft tissue to adsorb the impact. But a strike at an angle of less than 15 degrees can potentially fracture a bone with about 375 joules of kinetic energy (277 foot-pounds of force). Keep in mind that each bone in the human body, had different masses and different amounts of padding.
