natural frequency of a pinned beam
natural frequency of a pinned beam
(OP)
Can any one tell me how to work out the natural frequency of a beam pinned at both ends and subject to axial tension?
Thanks

Another option is the Vibrations HandBook which is a three volume set.

(p/L)*sqrt[(p^2EI/L^2+T)/m]
where
p = pi
L = length of bar
E & I = the usual
m = mass per unit length
T = axial tension
Unfortunately I do not have ready access to the Timoshenko book suggested by rlnorton above, but this result looks and smells right. (It gives the right result when the axial compression equals the Euler buckling load, and it gives the classic frequency for a taut string when EI is zero.)
