In a dynamic situation the vector sum of the forces acting on the body vanished as in the static case . 在動(dòng)力學(xué)狀態(tài)下,作用在物體上的力的矢量和與靜力學(xué)情形一樣化為零。
In an infinite dimensional space there always exist two subspaces whose vector sum is different from their span . 在一無限空間中恒存在兩個(gè)子空間,其矢量和與其張成空間不同。
Any two vectors whose vector sum equals a given vector are called the components of that vector . 假如任意兩個(gè)矢量的和等于一個(gè)給定的矢量,這兩個(gè)矢量就稱為該給定矢量的分量。
As mentioned above, we have not explicitly used the first condition for equilibrium, that the vector sum of the forces be zero . 如上所述,我們沒有直接應(yīng)用第一平衡條件,即力的矢量和為零。
