【Abstract】 The concepts of virtual displacement,real displacement and generalized coordinate are summarized.The difference between virtual displacement and real displacement,the direction and number of virtual displacements,the relationship between virtual displacements and real displacement were analyzed using analytic method.Finally an important condition for determining generalized coordinates is illustrated by example.更多还原
