Theorem of composit velocity of a moving point in combinatorial transport motion |
| |
Abstract: | There is not an adaptive theorem for composit velocity when a point moves in the case of combinatorial transport motion so far. The theorem of composit velocity of a moving point in combinatorial transport motion is introduced and two probative methods are provided in the paper.The theorem develops the original theorem that is based on only one transport motion.The method is more concise and has an obvious academic significance and a wide practical application. |

Keywords: | combinatorial transport motion motion coordinate system velocity composite transport velocity relative velocity |
