## What's Under the ANSYS Blackbox?

To understand the framework of what's under the ANSYS blackbox, go throu= gh the videos in the = =E2=80=9CWhat=E2=80=99s Under the Blackbox=E2=80=9D section of our free online course o= n ANSYS-based simulations. Registration is required to access this course. = We'll be using this framework in this tutorial.

## Hand Calc= ulations

One or more of the following statements is/are true. Select which statem= ents are true.

• 3D Elasticity theory makes the assumption that plane sections remain pl= ane whereas the Euler-Bernoulli beam theory doesn=E2=80=99t make this assum= ption.
•  In Euler-Bernoulli beam theory, the Poisson's ratio is assumed to= be zero.
• If we have 4 nodes instead of 3, ANSYS will need to determine 8 paramet= ers (4 y-displacements and 4 rotations) either from the essential boundary = conditions or by solving a set of algebraic equations.
• If we have 4 nodes instead of 3, the number of algebraic equations that= ANSYS will need to solve simultaneously will be 5.
• We have to determine the y-displacement of the midline at locations bet= ween the nodes using interpolation. This interpolation is given by a second= -order polynomial.
