Dynamic Behavior and Stability of Closed-Loop Control Systems
Chapter 11
In this chapter we consider the dynamic behavior of processes that are operated using feedback control. This combination of the process, the feedback controller, and the instrumenta

Rigid Bodies
-A rigid body is an ideal object that has
dimensions and mass but does not deform
under loading.
-The size and shape does significantly affect the

Amine
Since amines are derived from
ammonia (NH3), it is not surprising
that it gives off an unpleasant odor.
Some of the examples:
