A sitting person is pulling a rope with a force F. The working line of the pulling force runs through the point S. On the torso, a gravitational force G 3.9 is also working, which can be assumed to act on point M. The following points are given, with respect to the basis {ex, ey, ez}. point O: ko = 30ēx + 30ey [cm] point M: iм 3D20ёх + 50гу [em] point S: 10e + 70e [cml
