Pre-Analysis and Start-Up

...

Now we need to specify what type of material we are working with. Double click Engineering Data and it will take you to the Engineering Data Menus.

...

If you look under the Outline of Schematic A2: Engineering Data Window, you will see that the default material is Structural Steel. The Problem Specification specifies the material's Modulus of Elasticity and Poisson's ratio. To add a new material, click in an empty box labeled Click here to add a new material and give it a name. We will call our material Cornellium.

...

On the left hand side of the screen in the Toolbox window, expand Linear Elastic and double click Isotropic Elasticity to specify the Elastic Modulus and Poisson's Ratio.

...

In the Properties of Outline Row 4: Cornellium window, Set the Elastic Modulus units to psi, set the magnitude as 29e6, and set the Poisson's Ratio to .3.
