An instrument package A is bolted to a shaker table as shown. The table moves vertically in simple harmonic motion at the same frequency as the variable-speed motor which drives it. The package is to be tested at a peak acceleration of 150 ft/s2 . Knowing that the amplitude of the shaker table is 2.3 in., determine
(a) the required speed of the motor in rpm,
(b) the maximum velocity of the table. 19.9 The motion
