在水平面上相靠的两个相同的物体,它们之间是否有弹力作用? 回答应是不一定,这要看相靠的情况和水平面是否光滑等因素而定。因为,使两物体“相靠”的过程中,需要有水平方向的外力作用在物体的外侧(如图),这时,两物体相向的面发生接触(相靠),从而产生形变就有弹力产生。当外力撤去后就会出现多种情况。 Is there an elastic effect between two identical objects that rest on a level surface? The answer should not be necessarily, depending on factors such as dependencies and whether the level is smooth or not. Because, in the process of bringing the two objects “together”, it is necessary to have external forces in the horizontal direction acting on the outside of the object (as shown in the figure). At this time, the opposite surfaces of the two objects come into contact with each other, and thus the elastic deformation occurs. produce. When the external force is removed, there will be many situations.
