On the Virtual Displacement and It's Caculation |
| |
| Abstract: | This paper deals with combination of virtual displacement and variation of function. By meansof variational caculation we systematically discuss the relation between virtual dispacement and variation, necessary conditions required by vurtual displacement. Furthermore,a deduction is obtained, which leads to the kinbetic energy theorem of material particle system. |
