5 / 10

From the Harmonic Response analysis, what is the frequency at which peak amplitude is observed? Select the option that is closest to the result you obtained.

6 / 10

If the magnitude of both the Force loads was increased by 100N, what would be its effect on the mode shapes and corresponding natural frequencies? Choose the best option without rerunning the model.

7 / 10

From the Directional Deformation result, what is the absolute maximum amplitude of deformation reported when calculated with maximum spatial resolution? Select the option that is closest to the result you obtained.
