20th Century Graphical and Numerical Methods
With the rapid growth of rotating machinery from the beginning of the 20th century, there was a need to determine the natural frequencies in an industrial environment by rapid means that can be established to handle various design problems. Methods were devised to streamline and develop fool-proof methods which semi-skilled engineers could handle in the shortest possible time with minimum errors. These methods continued to play a significant role until recently; they are only now being phased out in industry in favor of finite element methods.
