It is impossible to stress the relevance of this omnipresent structural element
that is the beam. Aiming at applications regarding the safety of structures, it
is important to measure the properties of a beam like rigidity, to detect the
presence of defects and to identify the loading acting over a span of a beam.
Here we present a result that permits the unique determination of the rigidity
of a vibrating beam by measuring the displacement of it at one of its extremes
during an arbitrary small interval of time.
