Gnathodynamometer. A gnathodynamometer (or occlusometer) is an instrument for measuring the force exerted in closing the mouth. This device can measure the bite force of humans in the following three measurements: newtons, (N), pounds, (lb), or kilograms, (kg). The average bite force of a human being is 140 pounds per square inch, (psi).
Bite force quotient (BFQ) is a numerical value commonly used to represent the bite force of an animal, while also taking factors like the animal's size into account. The BFQ is calculated as the regression of the quotient of an animal's bite force in newtons divided by its body mass in kilograms. [ 1 ]
Orders of magnitude (pressure) This is a tabulated listing of the orders of magnitude in relation to pressure expressed in pascals. psi values, prefixed with + and -, denote values relative to Earth's sea level standard atmospheric pressure (psig); otherwise, psia is assumed. Magnitude. Pressure. lbf/in 2 or dB.
The jaw elevator muscles develop the main forces used in mastication. The force generated during routine mastication of food such as carrots or meat is about 70 to 150 newtons (16 to 34 lbf ). The maximum masticatory force in some people may reach up to 500 to 700 newtons (110 to 160 lbf ). [1] : 156. The study of masticatory force in patients ...
6.894757 kPa. The pound per square inch (abbreviation: psi) or, more accurately, pound-force per square inch (symbol: lbf/in2 ), [1] is a unit of measurement of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force with magnitude of one pound-force applied to an area of one square inch.
The bite force is considered the highest of any living or fossil fish, and among the highest of any animal. [31] The pressures generated in those regions were high enough to puncture or cut through cuticle or dermal armor, [ 31 ] suggesting that D. terrelli was adapted to prey on free-swimming, armored prey such as ammonites and other placoderms.
The Tasmanian devil has the most powerful bite relative to body size of any living mammalian carnivore, with a Bite Force Quotient of 181 and exerting a canine bite force of 553 N (56.4 kgf). [ 41 ] [ 42 ] The jaw can open to 75–80 degrees, allowing the devil to generate the large amount of power to tear meat and crush bones [ 38 ...
The bite force of Deinosuchus has been estimated to be 18,000 N (1,835 kgf; 4,047 lbf) [9] to 102,803 N (10,483 kgf; 23,111 lbf). [21] Deinosuchus had a secondary bony palate, which would have permitted it to breathe through its nostrils while the rest of the head remained submerged underwater. [22]
