Question
Military specifications often call for electronic devices to be able to withstand accelerations of 10 g. To make sure that their products meet this specification, manufacturers test them using a shaking table that can vibrate a device at various specified frequencies and amplitudes. If a device is given a vibration of amplitude5.1 cm, what should be its frequency in order to test for compliance with the 10 g military specification? The acceleration of gravity is 9.81 m/s2. Answer in units of Hz
Explanation / Answer
maximum angular frequency is 2A
10 * 9.81 = 2 * 0.051
= 43.858 rad/s2
Frequency = /2 = 6.984 Hz
