An analog computer study of a torsional vibrations problem

TORSIONAL VIBRATION studies of simple mechanical systems are usually handled by methods which, while not difficult, often require the expenditure of considerable time when done by hand. The use of a digital computer shortens the time considerably. One method frequently used is the Holzer table calculations1 resulting in the determination of the natural frequencies of the system. Another method is a matrix solution of the differential equations of the system.
