It is established that the general iteration formulas of the moving point coordinates.
计算了典型的单机开式复合约束绳系的动点坐标、绳力、吊点反力。
So, OK, so apart from that, I claim now we can find the position of its moving point Q0Q1 because, well, this vector, Q0Q1 we can find from the coordinates of Q0 and Q1.
不管那些了，我断言我们可以找出移动点的位置了,因为对于向量1,我们可以找出Q0和Q1的坐标。
