Abstract:

Estimates are made of the smallest nonzero frequency of vibration of undamped linear mechanical systems having lumped andor distributed mass and permitting rigid body motions. The approximations are smaller than the correct values but remarkable accuracy may be achieved. The procedures are based upon methods of S. Dunkerely and S. G. Mikhlin. Author
