TL;DR: In this article, the authors derived the natural frequencies and modes of rotating rings without using the inextensional assumption and an attempt was made to interpret the time dependent natural modes from various viewpoints.

TL;DR: Vibrational properties of thin rectangular plates continuous over intermediate rigid simple supports and simply supported along two opposite edges with simply supported and/or clamped end conditions have been calculated by using the receptance method as mentioned in this paper.

TL;DR: In this article, the authors used the mechanical impedance measurement technique to obtain data necessary to determine the vibration characteristics of the human hand and derived the values of the masses, springs and dampers for an equivalent mass-spring-damper system which simulates the dynamic response of the hand.

TL;DR: In this paper, the harmonic and periodic forced vibrations of rotating rings are derived and investigated, where the modal expansion technique yields the forced solution, which is characterized by four generalized co-ordinates associated with each n (circumferential wave number).

TL;DR: In this article, the authors investigated the walk of horizontal and vertical axis washers using dynamic models of these washing machine systems and found that the horizontal axis washer typically exhibits an oscillatory walk behavior in place while the vertical axis exhibited an unstable walk behaviour in the sense that the oscillating machine will move steadily in a direction dictated by the rotational direction of the basket.
