# SS-V: 2070 Cantilever Beam

Test No. VM08 Perform normal mode dynamic analysis of a cantilevered beam.

## Definition

The left end is fully constrained; the back face has a slider constraint to remove the third dimension.

The units are SI.

The material properties are:

**Properties****Value**- Modulus of Elasticity
- 2e
^{11}N/m^{2} - Poisson's Ratio
- 0.3
- Mass density
- 8000 kg/m
^{3}

## Results

The following table summarizes the
modes.
