Torsional Vibration

<p>ebook4 extends what you have been learning about SDoF axial vibrating systems into torsional vibrating systems. Interest in torsional vibration measurement and testing, also in torsional shock measurement and testing has increased dramatically in recent years. We briefly examine torsional equipment, less thoroughly than we examine axial vibration (and shock) equipment in ebooks 7, 8, 13, 15, 19, 23 and 30. After Book 4, we&rsquo;ll return to axial instrumentation, shakers and shock testing for the remainder of this Dynamic Environmental Testing ebook series. </p>
