Maximum displacement amplitude (stroke) =
5.0 cm
Maximum velocity amplitude = 150.0 cm·s–1
Maximum acceleration amplitude = 100.0 g

a. Would it be possible to obtain all three
of these peak performance capabilities simultaneously for this shaker? Explain.

b. On log–log paper that is used for
plotting response spectra, having frequency-velocity axes, mark the
capabilities of the shaker and the feasible test region. (This is called a
nomograph.)

c. If the shaker operates at a displacement
amplitude of 5.0 cm and a velocity amplitude of 150.0 cm·s–1,
simultaneously, what is the corresponding maximum acceleration amplitude that
would be possible? Also, what is the corresponding test frequency?

d. If the shaker operates at a velocity
amplitude of 150.0 cm·s–1 and an acceleration amplitude of 100.0 g,
simultaneously, what is the corresponding stroke that would be possible? What
is the corresponding test frequency?
