Kenny Yu EME 1 10/6/08 History of Mechanical Design The history of mechanical design dates back many centuries ago. In 1662, a mechanical engineer named Bockler invented the first water mill and discovered the principle of energy conservation. Before his invention most of the mills required grinding the wheel manually. Bockler’s design consisted of a water coil that wrapped around a pipe like a screw. This would keep the pipe turning and keep the mill running. In 1714, the British Parliament Board of Longitude offered prize money for whoever could invent an accurate marine chronometer. During this period, an accurate clock was very important for navigation and expeditions because to determine the longitude of a certain position is identified by using the Greenwich Mean Time. The time

Unformatted text preview: had to be pinpoint accurate because a one degree longitude error is approximately a seventy mile difference from the actual position. At this time, people had simple pendulum clocks which were not really accurate since the period of each oscillation is different. An engineer named Huygens solved this problem when he found a way to synchronize the pendulums. He conducted a process in which the amplitude of the pendulum would not affect the period of the oscillation. In 1769, James Watt invented the steam engine flyball governor which helped solve the problem with maintaining a constant speed of an engine. He developed a rotary engine that was powered by a piston. His innovation of the steam engine revolutionized the way people used automobiles....
