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.
If you really want to measure the power precisely, you mount the generator on gimbals and measure the torque with a scale on an arm. Or a big copper disk with electro magnets for drag. Or a drum (prony brake) filled with water and you measure the torque on its brake with a scale. You measure speed separately and you need both for power. Or you make a fan and spin it in air and someway you can compute the load based on the air temperature and the speed. Its harder to vary the load on the fan. Called a Baker fan. A disk brake from a train might be a good tractor prony brake too. Just measure the torque reaction on the brake mounting.
