I"ve heard (multiple times) the your finger is as simple to bite v as a carrot.

You are watching: How many pounds of pressure to bite off a finger

Here are some places I"ve seen it proposed:

Additionally, it is a popular question on Yahoo! answers. Nobody of these have specifically definitive, well-referenced answers.

I"ve heard story of people biting off fingers/toes of various other people. I"ve likewise heard your mind knows it would certainly hurt and also won"t allow you carry out it come yourself.

Is that true that fingers and carrots are fairly equivalent once it pertains to biting force?



A “newton” is the global unit that force. A human being adult’s best biting pressure ranges indigenous 520-1,178 newtons depending upon factors such together age and also gender. The requires less than 200 newtons to bite with a raw carrot. This is fine within the normal borders of the average person. Biting with a finger requires so much pressure that attempts often lead come partial-amputation; a bite that doesn"t fully sever the finger. There are instances of fingers being bitten totally off, however such one act requires extraordinary force, far greater 보다 200 newtons the carrot-cutting power.

You"ll still need to bite with skin, tendons, and some flesh.Skin, unlike "meat", is really elastic. It"s similar to trying to bite a rubber band instead of a carrot.There are a lot of of determinants that contribute to mechanical failure, applied force is only one :)

according to this research done in 1956 (Jamming that fingers: an speculative study to identify force and also deflection in participants and human cadaver specimens for advancement of a new bionic test device for validation the power-operated motor vehicle side door windows) cadavers bones were tested in ~ maximum applied force that 1886 N for the index finger and 1833 N because that the little finger. In 200 jam positions, 25 fractures to be observed on radiographs; fractures developed at an average force of 1485 N.

So if that takes 1485 newtons to cause fractures (obviously greater force is required to completely sever with the entire fingers) climate it does no take the same force to bite with a finger as a carrot.

Was wondering if girlfriend were waiting to mark this as the answer. I re-read your comment and also realized you may have actually been waiting on a difficult number for human being bite force and also the pressure required to sever the finger.

For human bite force: the Wikipedia short article on assignment of magnitude tells united state that human bite force, measured at the molars is average at 720 N. As much as understanding what that would take to sever a finger you have to understand just how measurements of hardness room taken (and the different scales used, yet I won"t enter that.)

According to the Wikipedia article on Hardness: Hardness is a measure up of just how resistant solid matter is to assorted kinds of long-term shape readjust when a force is applied. Hardness is dependent on ductility, elastic stiffness, plasticity, strain, strength, toughness, viscoelasticity, and also viscosity. There space three main varieties of hardness measurements: scratch, indentation, and rebound. Within every of this classes of measurement there room individual measure up scales.

Scratch hardness is the measure of exactly how resistant a sample is to fracture or long-term plastic deformation because of friction indigenous a sharp object.

Indentation hardness actions the resistance that a sample to material deformation because of a continuous compression pack from a sharp object.

Rebound hardness, also known as dynamic hardness, procedures the elevation of the "bounce" the a diamond-tipped hammer dropped native a fixed height onto a material. This kind of hardness is regarded elasticity.

All the being said, the manner in i beg your pardon the finger is severed, it is in it stripping the the meat from the bone vs. A clean cut vs. Blunt force crushing/obliterating, renders answering the concern of "how much" pressure is compelled to "sever" a finger from the body difficult. I hope this answers your concern in enough detail to dispel any kind of skepticism that the human being finger can be severed as conveniently as a carrot through the human mouth.

(For purposes of this answer I have not researched details data regarding macroscopic molecular bonding of the biological materials that consist of the person finger. Possibly a thesis is in order?)
