+** On the relevance of constraining in dynamic analyses **
+[[https://www.youtube.com/watch?v=0GEj69NANc8|back view]] [[https://www.youtube.com/watch?v=RihcJR0zvfM|side view]] relevance of (improper) constraints on the dynamic behaviour of a structure.
+Design is reliable in actual operational conditions ([[https://en.wikipedia.org/wiki/Boeing_CH-47_Chinook|link]]).
+Added constraints stiffen up the structure, thus increasing natural frequencies.
+However, a 0 Hz rigid body mode natural frequency may rise to a finite value due to added positioning constraints; the associate natural mode may be excited in resonance by dynamic loads.
