Use this form to estimate the bending of a cantilever beam with an
end mass due to an acceleration load. The acceleration is applied
perpendicular to the plane of the beam. This is similar to an
accelerometer. An acceleration load of 1g is equivalent to the
weight of the mass acting on the beam. The maximum stress is at the
top surface near the clamped edge and the maximum deflection is at
the free end.
The X-Y plot shows the variation of maximum
stress with change in the acceleration load. Using the crosshair,
the maximum stress for any acceleration load from 0.1g to 100g can
be calculated. The 2D and 3D surface plots show the deflection of
the beam due to the load.
-The default material is Silicon with a Young's modulus of
-The beam has uniform cross section.
-The bending of the mass is negligible.
-The deflection of the beam due to the weight of the mass is not
-No other load acts on the structure other than the acceleration
load perpendicular to the plane of the beam.
-Damping is not considered.
