Bending of a double clamped beam under its distributed weight

len         length of the beam in µm
wid        width of the beam in µm
thc         thickness of the beam in µm
den        density of the material in kg/m3
ymod     Young's modulus of the material of the beam in GPa
sel         number denoting the selected result.
              Use 1 for maximum stress and 2 for maximum deflection and 3 for spring constant of the beam

Notes

Use this form to estimate the bending of a double clamped beam under its own weight. The maximum stress is at the top surface near the clamped edge and the maximum deflection is at the middle of the beam. The deflection plot of the beam under its weight is provided.

Assumptions

-The default material is Silicon with a Young's modulus of 180GPa.
-The beam has uniform cross section.
-The weight of the beam is uniformly distributed.
-There is no other load acting on the beam other than its own weight
