4 / 10

When using line bodies (beam elements), we may be interested in plotting equivalent stress on the beam. Select the best option below that is a correct statement for this model.

Equivalent stress can be plotted on line bodies if “Beam Section Results: Yes” is set in the Solution Details view.

Equivalent stress cannot be plotted on line bodies.

Equivalent stress can be plotted on line bodies using the Beam Tool.

Equivalent stress can be plotted on line bodies using the Stress Tool.

5 / 10

Using the Beam Tool, compare the Direct and Bending Stresses. Select the best option that is correct.

The largest magnitudes of the direct stress and bending stress are comparable.

The largest magnitude of the bending stress is much smaller than the largest magnitude of the direct stress.

It is not possible to compare the direct and bending stresses directly, as only combined stresses are available.

The largest magnitude of the bending stress is much greater than the largest magnitude of the direct stress.

0.5 mm

4.5 mm

1.5 mm

7 / 10

Add a Reaction Force result object and review the total Reaction Force acting on the tent. What is the total Reaction Force in Y direction? Select the option which is closest to the correct result.

100 N

650 N

500 N

0 N

8 / 10

For this model, what might be needed to be done in SpaceClaim to ensure that nodes will be shared when meshed in Mechanical? Select the best option. 

Use Shared Topology to ensure that intersecting beams share the same node

Move the beams so that they are in the same plane

No extra steps are needed in SpaceClaim, as Mechanical automatically creates shared nodes

Align cross section of the beams to share points where beams intersect

9 / 10

Add a Reaction Force result object and review the total Reaction Force acting on the tent. Based on the reaction force in the Y direction, select the correct statement from the following mentioned.

The person’s weight is comparable to the weight of the tent structure.

The weight of the person is much larger than the weight of the tent structure.

The reaction force has no relation to the weight of the tent structure or to the person’s weight.

The weight of the tent structure is much larger than the weight of the person.

10 / 10

When using line bodies (beam elements), we may be interested in evaluating stress components (normal and shear). Which of the following statements is correct concerning this model?

If one wants to interpret all beam stresses in a particular coordinate system other than the global Cartesian coordinate system, this must be specified prior to solving.

Beams do not have normal or shear stress component output, as they only have direct and bending stresses.

When evaluating beam section results, one can transform beam stress components into different coordinate systems, such as cylindrical coordinate systems.

When evaluating beam section results, stress components are always interpreted in the Solution Coordinate System, regardless of the “Coordinate System” setting of the stress result object.
