SS-V: 2060 In-plane Vibration of Pin-ended Cross
Test No. VM07 Find the first eight modal frequencies for in-plane vibration of a cross with pin joints at the ends.
Definition

Pins are simulated via zero displacements applied to a straight line. The front surface of the cross is fixed from out-of-plane displacements.
The units are SI.
The material properties are:
    - Properties
 - Value
 - Modulus of Elasticity
 - 2e+11 N/m2
 - Poisson's Ratio
 - 0.3
 - Mass density
 - 8000 kg/m3
