    • A method of applying a plurality of forces to a physical component in response to an external force being applied to the physical component, wherein: - each respective one of the plurality of forces is being applied at a respective one of a plurality of predetermined different locations at the physical component; - the plurality of forces are higher in number than a minimum number needed to counteract a displacement of the physical component as a result of the external force and to counteract a change of orientation of the physical component as a result of the external force; - the method comprises applying the plurality of forces by: (i) controlling the plurality of forces so as to counteract the external force and achieve force equilibrium and moment equilibrium of the physical component; and (ii) controlling the plurality of forces so as to control an elastic deformation of the physical component at a region-of-interest at the physical component, the plurality of forces being controlled dependent on at least one of: a further location on the physical component at which the external force is being applied to the physical component, a magnitude of the external force, a direction of the external force and an estimated elastic deformation of the physical component at the region-of-interest, the elastic deformation occurring as a result of the plurality of forces and of the external force being applied.
    • 响应于施加到所述物理部件的外力而将多个力施加到物理部件的方法,其中: - 所述多个力中的每个相应的一个力被施加在多个预定的不同位置中的相应一个 在物理组件; - 所述多个力的数量高于由于外力而抵消物理部件的位移所需的最小数量并且抵消由于外力而导致的物理部件的取向的改变; - 所述方法包括通过以下步骤施加所述多个力:(i)控制所述多个力以抵消所述外力并实现所述物理部件的力平衡和力矩平衡; 以及(ii)控制所述多个力,以便控制所述物理部件处的感兴趣区域处的所述物理部件的弹性变形,所述多个力被控制取决于以下中的至少一个: 外力施加到物理部件的物理部件,外力的大小,外力的方向以及物理成分在感兴趣区域的弹性变形,弹性变形发生为 施加多个力和外力的结果。
