So if a mode only tells you about the possible motion of a structure, how do you know which mode best describes the beam's motion? I know that such a vibrating system can have multiple modes but is it possible for some modes to have little or no effect on the response? How do you know which ones...
Hello, I am taking a vibrations course and we are currently talking about using PDEs to find responses of beams. In the book, there is an equation to find the natural frequencies of a simply supported beam under an axial load:
omega = (pi^2/l^2)*sqrt(EI/roA)*sqrt(n^4 + (n^2*P*l^2)/(pi^2*EI))...
Homework Statement
Hello, I would just like to make sure I am doing the problem correctly. What I have is a cantilever uniform beam that is fixed at one end and free on the other. Basically, it is a wing and I am using a lumped mass approach to find a graphical representation of the wing's...
