Vibrations of Multi-degree-of-freedom Systemss a natural development from the single-degree-of-freedom systems analysed in the previous chapter, particular attention will be paid to the treatment of two-degree-of-freedom vibrations. The methods developed can then be extended to the multi-degree-of-freedom cases.

Kinematics is concerned with the way in which bodies move and is essentially a branch of pure geometry. It deals with the relationships between displacement, velocity and acceleration, and the variation of these quantities with time. In this section, the study is confined to that of a particle and of a line.

Robotics and Controld ethical issues to the problems. Many of these difficulties and dangers can be relieved by the use of ., devices which, properly designed, can operate faster, with greater accuracy and reliability, and with less fatigue, than their human counterparts, to give greater work output of a more consistent quality with increased safety.
