CSWP Assembly Mass Properties Analysis 5

Question 1

In a SolidWorks assembly mass properties dialog, what does the 'Accuracy' slider control?

Accepted Answer

The tessellation refinement used to approximate curved surface volumes

Answer

The Accuracy slider adjusts the mesh tessellation quality used to approximate volume for curved geometry, trading speed for precision.

Question 2

A CSWP problem states that the density of a custom material is 7,850 kg/m³. If you are working in the MMGS unit system, what density value should you enter in SolidWorks?

Accepted Answer

0.00785 g/mm³

Answer

7,850 kg/m³ converts to 0.00785 g/mm³ because 1 kg/m³ = 0.000001 g/mm³, so 7,850 × 0.000001 = 0.00785 g/mm³.

Question 3

Which SolidWorks tool is specifically designed to automatically update a linked mass value in a drawing annotation whenever the assembly mass changes?

Accepted Answer

Bill of Materials with mass column

Answer

A Bill of Materials with a mass column linked to the SolidWorks Mass property automatically reflects updated masses when the drawing is regenerated.

Question 4

In SolidWorks, which assembly-level operation would cause the center of mass to shift without changing the total mass of the assembly?

Accepted Answer

Moving a component to a different position using mates

Answer

Repositioning a component via mates changes where its mass is located spatially, shifting the assembly's center of mass without altering total mass.

Question 5

When a SolidWorks part contains multiple bodies (multibody part), how does the Mass Properties tool handle them when the part is used in an assembly?

Accepted Answer

All solid bodies in the part contribute to the assembly mass

Answer

All solid bodies within a multibody part contribute their individual volumes and masses to the assembly's total mass properties.
