单词 | statics |
释义 | staticsn. 1. Usually with singular agreement. a. Originally: †the science dealing with weight and its mechanical effects, and with the conditions of equilibrium resulting from the distribution of weight (obsolete). In later use: the branch of physical science concerned with the action of forces in producing equilibrium or relative rest, and with the forces acting on systems and structures in equilibrium.Statics has been contrasted with dynamics, kinetics, and kinematics.
