Their massive jaws can open up to 180 degrees, and they can bite down with a force three times greater than a lion. As herbivores, hippos peacefully graze throughout the night, eating grasses and ...
Bite force quotient (BFQ) is a numerical value commonly used to represent the bite force of an animal adjusted for its body mass, while also taking factors like the allometry effects. 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 ]
france hippo But a video that's getting attention on Digg will bring you back to reality -- and it'll blow your mind. The footage shows a man in Japan giving the hippos a not-so-little treat.
On the National Geographic Channel television program, "Dangerous Encounters with Brady Barr", Dr. Brady Barr measured the bite force of an adult female hippo at 8,100 newtons (1,800 lbf); Barr also attempted to measure the bite pressure of an adult male hippo, but had to abandon the attempt due to the male's aggressiveness.

The basic reason is allometry. Bite force scales with weight, but the relationship isn't quite linear. So a theoretical animal with a bite force of 100 Newtons and a mass of 1 kilogram would have a BFQ of 100 N/kg^(2/3). If it had a bite force of 400 Newtons, and weighed 8 kg, it would still have a BFQ of 100 N/kg^(2/3).

The Force Concept Inventory is a test measuring mastery of concepts commonly taught in a first semester of physics developed by Hestenes, Halloun, Wells, and Swackhamer (1985). It was the first such " concept inventory " and several others have been developed since for a variety of topics.
