Do internal / external stresses affect modal frequency?
Imagine a cantilevered beam, fixed on one end and with a tension line connecting the other end to ground (e.g. perpendicular to the length of the beam). … So, would pulling on the beam (in tension) cause it to have a higher frequency?
On the other hand, the bending stiffness of a beam is not affected by a lateral force. …
