resonant frequency

Calculate the theoretical first resonant frequency of the beam with the following information.

ai coefficients = (3.526 , 22.03 , 61.70 , 120.91 , 199.85)

Beam Length (L) = 11.5 inch

Beam width (b) = 1.0 inch

Beam thickness (h) = 0.125 inch

 

Use young's modulus and density for 7075 aluminum.

 

Mass per unit length is ​m​¯​​

 

Natural frequency is: f​i​​(a​i​​)=​2π​​a​i​​​​√​​​m​¯​​L​4​​​​EI​​​​​

 

Moment of Inertia is: I=​12​​bh​3​​​​
