2. In many mechanical positioning systems there is flexibility between one part of the system and another. The figure below depicts such a situation, where a force u(t) is applied to the mass M, and another mass m is connected to it. The coupling between the objects is often modeled by a spring constant k with a damping coefficient b, although the actual situation is usually much more complicated than this. y(t) m M ut) no friction no friction a)...
