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/s . 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.
