Collagen is the main component of connective tissue, and is the most abundant protein in mammals, making up about 25% to 35% of the whole-body protein content. An atomic-force-microscopy image of collagen fibrils in a collagen fiber.ollagen is a protein made up of amino-acids, which are in turn built of carbon, oxygen and hydrogen. Collagen contains specific amino acids â Glycine, Proline, Hydroxyproline and Arginine.
These 10 animal facts will amaze you. The Prony brake is a simple type of dynamometer used to measure the amount of torque produced by a motor or engine in order to determine its brake horsepower rating. The device was invented in 1821 by a French engineer named Gaspard de Prony, and continues to be widely used by tractor and heavy equipment manufacturers.
1 Brake horsepower generally means that the power was measured on a type of dynamometer called a prony brake (sometimes incorrectly called a pony brake--prony refers to the inventor, Gaspard de Prony).  2 Drawbar horsepower, used in railroad applications.  3 Air horsepower, used in fan calculations.otice that although Engine B has more peak horsepower, Engine A has more power at speeds up to 5500 rpm. What's more, it has significantly more power in the 1500-4000 rpm range (highlighted area), the range of engine speeds in which you'd typically operate a car. Now let's look at the torque curves of the two engines:
