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 180GPa.
-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 considered.
other load acts on the structure other than the acceleration load perpendicular
to the plane of the beam.
-Damping is not considered.
