vibration. If forces are applied left of the node of vibration such as illustrated in
Fig. 7b
the
vibratory system will respond in the direction of the forces applied. If, however, the forces are
applied in the node of vibration as illustrated in
Fig. 7c
the vibratory system will maintain a
state of rest.
The simplified Figures below do not include the springs.

The vibratory system as illustrated in
Fig. 8
is the basis of a force measuring system.
Basically it would be enough to replace one of the two springs by a transducer as shown in
Fig. 8
. Following Figures 7 this transducer will not supply a signal if the centrifugal force acts
on the node of vibration (point no. 1). If acting on any other points (nos. 2 and 3) the forces
will produce a signal which is proportional to
a
F
⋅
. The displacement of the node of vibration
as a result of the force measuring system during vibrations can be neglected.
