CSWA - Certified Solidworks Associate Materials and Mass Properties Questions and Answers

Question 1

A SolidWorks user needs to determine the total mass of a part. After modeling the geometry accurately, which of the following steps is absolutely essential to get a correct mass calculation?

Accepted Answer

Assign the correct material to the part.

Answer

Create a custom coordinate system at the part's origin.

Answer

Ensure all sketches are fully defined.

Answer

Run a simulation study on the part.

Question 2

You are given a part file and asked to report its Center of Mass in millimeters, relative to a specific corner which is not the default origin. Which combination of SolidWorks tools would be the most efficient way to accomplish this?

Accepted Answer

Create a new Coordinate System at the specified corner, then use the Mass Properties tool and report values relative to the new system.

Answer

Use the Measure tool to find the distance from the origin to the corner, then manually calculate the offset.

Answer

Assign a new material with a density that shifts the center of mass to the desired corner.

Answer

Edit the original sketch and move the entire geometry so the desired corner is at the origin.

Question 3

In the Mass Properties dialog box, a user wants to view the calculated mass in kilograms, but the part was modeled using millimeters and the default units are grams. Which of the following is the correct procedure?

Accepted Answer

Click 'Options' in the Mass Properties window and use the 'custom settings' to change only the mass unit to kilograms.

Answer

Change the part's global unit system in Document Properties to MKS (meter, kilogram, second).

Answer

Manually divide the resulting gram value by 1000.

Answer

Use the 'Override Mass Properties' feature and re-enter the mass value with 'kg' units.

Question 4

A material required for a design has a specific density of 7.85 g/cm³. This material is not available in the default SolidWorks material library. What is the proper first step to use this material for mass calculations?

Accepted Answer

Find a similar material in the library, copy it to a custom library, and edit its density value.

Answer

Select the closest available material, like a generic steel, and use the 'Override Mass Properties' tool to input the correct final mass.

Answer

Model the part with no material assigned and use the Measure tool to find the volume, then calculate mass manually.

Answer

Change the global document units to match the density units.

Question 5

Which of the following values is NOT directly available in the main report of the Mass Properties tool?

Accepted Answer

Yield Strength

Answer

Total Volume

Answer

Center of Mass coordinates

Answer

Principal Moments of Inertia

Question 6

A user has a multibody part and needs to find the mass of only one specific solid body within that part. How can this be achieved using the Mass Properties tool?

Accepted Answer

Select the desired solid body in the graphics area or FeatureManager tree *before* opening the Mass Properties tool.

Answer

The tool can only calculate the properties for the entire part file.

Answer

Hide all other bodies, then run the Mass Properties tool.

Answer

Use the 'Override Mass Properties' tool and select the single body.
