Use 2 for first modal frequency

**Notes**

This design interface can be used to determine the fundamental
frequency of vibration of a double-clamped beam. The two ends
of the beam are rigidly fixed. For this analytical solution, width
of the beam has only minimal influence on the fundamental frequency
of vibration.

The plot shows the amplitude frequency relationship for the given beam. It shows the first resonance frequency as a sharp rise in amplitude. Using the cross hair tool, the resonant frequency and the corresponding relative amplitude can be obtained.

-The default material is Silicon with a Young's modulus of 180GPa and Poisson's ratio of 0.3.

-The beam has uniform cross section.

-The weight of the beam is uniformly distributed.

-The property of the material remain constant across the beam length.

-Damping is not considered.
