All complex and intricate assemblies include components with natural frequencies that are critical because they exist in the generalized 8 to 200 Hz environmental spectrum. This can be demonstrated by ...
There are natural frequencies in all equipment that have components. Generally, they exist in the 8 to 200 Hz environmental spectrum. Figure 46.1 demonstrates the transmissibility and resonant ...
In this lecture we discovered the principle of “reciprocity” for the static deflection of linear systems. The MATHEMATICAL consequence: The flexibility matrix [A] is symmetric. The COMPUTATIONAL ...
