Machine, derived from the Greek Mechine and the Latin Machina, originally referred to as "ingenious design", as a general mechanical concept, dating back to the Roman period, mainly to distinguish between hand tools. The term "mechanical" in modern Chinese is the general term for the mechanism of English and Machine. Mechanical features are: Mechanical is a combination of artificial physical components. There is a defined relative motion between the various parts of the machine. In addition to the characteristics of the machine, the machine must also have a third feature that can replace human labor to complete useful mechanical work or convert mechanical energy, so the machine can convert mechanical energy or complete useful mechanical work, which is the most basic in modern mechanical principles. The concept of modern Chinese mechanical concept is mostly derived from the Japanese word for "mechanical". Japanese mechanical drinking supplies define the mechanical concept as follows (that is, the following three characteristics are called mechanical Machine): 1. A machine is a combination of objects, and it is difficult to deform assuming that a force is applied to each part thereof. 2. These objects must achieve mutual, single, defined movements. 3. Transform the applied energy into the most useful form or transform it into effective mechanical work. end glow fiber optic,End lit PMMA fiber,fiber optic light pipe Jiangxi Daishing POF Co.,Ltd , https://www.jxopticfibrelight.com
End emitting fibers (also called end glow, or end light) are the classic fiber optics, with bright points of light at the ends and very little light escaping along the strands themselves. They are usually thin, somewhere from 0.25 to 3mm in diameter. They are also generally stiffer than the side emitting fibers.
