1.
What is the main purpose of David and Jessica’s conversation?
To explain how to validate an FEA model using test data
To discuss how to design a new physical test program
To plan a budget for future model improvements
To compare two different engineering software tools
Explanation:
The conversation focuses on validating an FEA model by comparing it with physical test data, checking outputs, and documenting the process.
2.
According to David, which outputs should be compared with the physical test data?
Temperature and pressure values
Voltage and current values
Speed and acceleration values
Stress and displacement values
Explanation:
David says, ‘Those are key outputs to validate,’ referring to stress and displacement values.
3.
What should they check if the model results are different from the test data?
The company’s annual report
The color of the model plots
The names of the test technicians
Material properties and boundary conditions
Explanation:
David says that if the results differ from the test, they should check the material properties and boundary conditions.
4.
What can be inferred about the validation process from David’s advice?
It only needs one test if the first results match perfectly
It should be finished without any documentation
It depends mainly on personal preference rather than measurements
It may require more than one comparison before the model is accepted
Explanation:
David says more tests may be needed if differences remain, and that error margins and engineering judgment are used, which implies validation may take more than one comparison.
5.
Why does David tell Jessica to document all validation steps clearly?
Because the information will be useful for future reference
Because the test data are too expensive to repeat
Because Jessica asked for a written summary of the software
Because the model cannot be checked without it
Explanation:
David explicitly says, ‘Documentation is important for future reference,’ which is his reason for documenting the steps.
