Problem Specification — Lesson 1

Consider an aluminum beam that is clamped at one end, with the following dimensions.

Length 4 m
Width 0.346 m
Height 0.346 m

The aluminum used for the beam has the following material properties.

Density 2700 Kg/m^3
Young's modulus 70x10^9 Pa
Poisson's ratio 0.35

Using Ansys Workbench find the first six natural frequencies of the beam and the mode shapes.
