It is notable as the home of the U.S. film industry, including several of its historic studios, and its name has come to be a shorthand reference for the industry and the people in it. Hollywood was a small community in 1870 and was incorporated as a municipality in 1903. It was consolidated with the city of Los Angeles in 1910, and soon thereafter a prominent film industry emerged, eventually becoming the most recognizable film industry in the world.
Introduction. Traction is the use of weights, ropes and pulleys to apply force to tissues surrounding a broken bone. It's sometimes used to keep a broken leg in the correct position during the early stages of healing, or to ease the pain of a fracture while a person is waiting for surgery.
Traction can also refer to the maximum tractive force between a body and a surface, as limited by available friction; when this is the case, traction is often expressed as the ratio of the maximum tractive force to the normal force and is termed the coefficient of traction (similar to coefficient of friction).here seems to be some confusion in this statement about tracked vehicles and traction. A tank or similar tracked vehicle uses tracks to reduce the pressure on the areas of contact. A 70-ton M1A2 would sink to the point of high centering if it used round tires.
