WebOne was a beam freely supported at two nodal points, and A = beam cross-sectional area the other was a beam simply supported at the ends. These two systems have analytical solutions to the equations of motion and can be found The constants C1 to C4 must be determined from the boundary in the literature [2,3]. Web14 de feb. de 2024 · From Formula ( 1 ), the expression for the natural vibration frequency of a simply supported beam is: \omega_ {n} = (\frac {n\pi } {l})^ {2} \sqrt {\frac {EI} { {\overline {m}}}} \sqrt {1 - \frac {F} { {n^ {2} \frac { {EI\pi^ {2} }} { {l^ {2} }}}}} = \omega_ {n} \sqrt {1 - \frac {F} { {n^ {2} P_ {c} }}} (2) ewf 50fta
