CSWP Assembly Mass Properties Analysis 3

Question 1

When using 'Include hidden bodies/components' in the Mass Properties dialog, what effect does this have?

Accepted Answer

It includes bodies hidden using Hide/Show in the calculation

Answer

Checking 'Include hidden bodies/components' ensures bodies that are visually hidden are still counted in the mass properties result.

Question 2

For a CSWP exam scenario, if the assembly mass properties show the center of mass at X=15mm, Y=20mm, Z=10mm and you mirror the entire assembly about the YZ plane, what happens to the X coordinate of the center of mass?

Accepted Answer

It moves to X=-15mm

Answer

Mirroring about the YZ plane negates the X coordinate, so X=15mm becomes X=-15mm.

Question 3

Which SolidWorks feature allows you to add a point mass to a location in an assembly without modeling the actual geometry?

Accepted Answer

Point Mass (under Insert > Assembly Feature)

Answer

The Point Mass feature (Insert > Assembly Feature > Point Mass) adds a lumped mass at a specified location in the assembly.

Question 4

In a CSWP scenario, you need the moment of inertia about the center of mass rather than the origin. What does SolidWorks require you to use?

Accepted Answer

The 'Taken at the center of mass' option in Mass Properties

Answer

SolidWorks provides a 'Taken at the center of mass' option in the Mass Properties dialog to output inertia relative to the COM.

Question 5

If a component in a SolidWorks assembly uses a configuration with a different geometry than the default, which configuration's mass is used in the assembly mass properties?

Accepted Answer

The configuration active in the assembly context

Answer

SolidWorks uses the configuration that is currently active within the assembly, which may differ from the part's default configuration.
