Energy required to break various bones (measured in joules)?
I read in a book that a thrown knife posses sufficient energy to break an arm bone. That got me thinking about how much energy is required to break all the other bones in the human body.
The book is Pananandata Guide to Knife Throwing by Amante P. Marinas, Sr.
The title is pronounced (pana-nan-data)
The first chapter discusses the physics of knife throwing and states that the kinetic energy of a thrown knife that weighs 4.2 oz (0.12 kg) and is traveling at a velocity of 25 m/s is about 37.5 joules. The energy required to break an arm bone is about 18 joules.
Does anyone have any idea how much kinetic energy is required to break other bones? Please support your answers by citing sources and fully explaining how you got your answer.
One last thing I would like to add: I will NOT tolerate anyone answering for the sole purpose of gaining two points.
The Germans did a lot of work on that during WWII. The fellow who developd the Luftwaffe’s crash helmet did so by swinging weights against human skulls. He did not say if they were occupied at the time or not,and I did not ask. ( after the war, he was moved to the US as one of the vital intellectuals- like Werner von Braun– was a Prof at Johns Hopkins.) Anyway, you may find something in the old WWII literature. It is of no clinical consequence as a rule, tho it might be in Forensic Pathology occasionally. And I don’t want the two points.
