Question:

Suppose one of the supports is removed from the mass-spring chain of Exercise 9.6.19. Does your forcing function still excite the resonance? Do the internal vibrations of the masses
(i) Speed up
(ii) Slow down, or
(iii) Remain the same?
Does your answer depend upon which of the two supports is removed?
