Exercises
Learning goal: Critiquing computer results is an important engineering skill. To help you develop this "critical thinking" skill, this problem presents you with an ANSYS solution and asks you to critique it using hand calculations. We want you to tell us if the ANSYS solution provided in this problem has been set up correctly or if we are trying to bluff you. Enjoy!
Problem Statement: Go through the preceding Tensile Bar tutorial before attempting this exercise. A steel plate of width, w=0.25m, of length L=2m, and of density 7.9x10³kg/m³ is hung vertically from the ceiling. A force, F=50N is applied as shown in the figure below. The thickness is 1mm.

You can download our ANSYS FEA solution to this problem by clicking here. Load this Unzip the file and load the project into ANSYS Workbench as in the tutorial. Double-click on Results in Workbench to bring up the FEA results that have been calculated already.

You should see the following results under Solution:
- Displacement
- sigma_y (i.e. σ_y)
- sigma_x (i.e. σ_x)
You might need to change the units for the results display by selecting Units > Metric (m, kg, N, s, V, A).
1. Look at the Displacement plot. From this plot, deduce if the model is constrained properly. Show your reasoning.
