# Foundations in Linear Dynamics using Ansys Mechanical - Simulation Quiz 2

### Mode-Superposition Analysis of a Cantilever Beam

A cantilever beam is fixed at one end and is subjected to a linearly varying force for a short duration of 0.01 sec at the other end. Perform a transient mode superposition analysis and find the deformation of the cantilever during the time of 1 sec.

1 / 10

The model has a Force applied on the free end with 100 N acting in each of the X, Y, and Z directions. Select the option below that is a correct statement.

2 / 10

What is the maximum deformation seen during the transient analysis? Select the closest option.

3 / 10

Without solving the model, what will the maximum directional deformation in the Y-direction be if the applied force in the Y-direction is -200 N? Assume that forces in the X- and Z-directions remain unchanged. Select the best option.

4 / 10

Without modifying and solving the model again, consider changing the material to one with twice the current mass density (geometry, loads, and all other material properties remain unchanged). Select the best option that describes what happens with this new density to the Total Deformation response.

5 / 10

Without modifying and solving the model again, consider an increase in the plate thickness. Select the best option that describes what happens to the Total Deformation response.

6 / 10

The analysis used a damping ratio of 1%. If the damping ratio were increased to 5%, select the best option that describes the Total Deformation response.
