Figure 1. (a) A freely vibrating Timoshenko beam mounted on Pasternak foundation. The foundation is modelled as an in"nite series of massless vertical springs of sti!ness k 5 per unit length, connected at top by a shearing layer of shearing sti!ness k . per unit length.

In a recent and comprehensive Letter to the Editor [1] approximate explicit formulae have been derived by El-Mously for the fundamental natural frequency for vibration of Timoshenko beams mounted on Pasternak foundation. It is the purpose of this note to mention other previous works in which the ap
