# SS-V: 2090 Triangular Wing - Fixed Vibration

Test No. VM10 Perform a normal mode dynamic analysis of a fixed right triangular plate.

## Definition

The plate is 6 in long and 0.034 in thick.

The units are IPS.

The material properties are:

**Properties****Value**- Modulus of Elasticity
- 6.5e
^{6}lb/in^{2} - Poisson's Ratio
- 0.3541
- Weight density
- 0.06414 lb/in
^{3} - Mass density
- 1.66128e
^{-4}lb-s^{2}/in^{4}

## Results

The following table summarizes the
modes.

Reference | SimSolid | % Difference | |
