4 / 10

What is the minimum number of modes that needs to be extracted such that the ratio of effective mass to total mass along the direction of loading is at least 0.9? Select the best option.

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
