CSWP Assembly Motion and Detection 2 — Questions and Answers
Question 1: In a SolidWorks assembly, what does a 'LimitAngle' mate do when applied between two components?
- Locks the angle permanently between two faces
- Restricts angular rotation between two components within defined minimum and maximum values (Correct answer)
- Sets a fixed angle that cannot be changed without editing the mate
- Converts a rotational joint into a fixed joint
Correct answer: Restricts angular rotation between two components within defined minimum and maximum values
A LimitAngle mate allows angular motion between two components but constrains it within a user-defined minimum and maximum angle range.
Question 2: Which SolidWorks tool would you use to visualize the swept volume of a moving component during animation?
- Motion Study Results (Correct answer)
- Interference Detection with 'Treat coincidence as interference' enabled
- Physical Simulation sweep trace
- Assembly Visualization
Correct answer: Motion Study Results
Motion Study Results can generate plots and traces showing the path and swept volume of components during animation.
Question 3: When setting up a gear mate in SolidWorks, what input is required to define the gear ratio?
- The number of teeth on each gear
- The ratio of angular velocities between the two gear axes (Correct answer)
- The pitch diameter of each gear
- The module value of each gear
Correct answer: The ratio of angular velocities between the two gear axes
A gear mate uses the ratio of angular velocities (or equivalently pitch radii) to define how rotation of one gear drives the other.
Question 4: In SolidWorks Motion Analysis, what is a 'spring' element used for?
- Applying a constant force between two points
- Simulating elastic force proportional to relative displacement between two components (Correct answer)
- Locking two components at a fixed distance
- Replacing a concentric mate in dynamic simulations
Correct answer: Simulating elastic force proportional to relative displacement between two components
A spring element applies a force proportional to the displacement between two attachment points, simulating elastic behavior.
Question 5: Which mate type is used in SolidWorks to simulate a rack-and-pinion mechanism?
- Gear Mate
- Rack Pinion Mate (Correct answer)
- Linear/Linear Coupler Mate
- Screw Mate
Correct answer: Rack Pinion Mate
The Rack Pinion Mate links linear translation of a rack component to the rotation of a pinion component.
Question 6: In Collision Detection, what happens when 'Stop at collision' is enabled during manual component dragging?
- The component is automatically fixed in place after a collision
- SolidWorks stops the drag motion when the component contacts another body (Correct answer)
- An alert dialog is shown listing all interfering components
- The colliding components are highlighted red permanently
Correct answer: SolidWorks stops the drag motion when the component contacts another body
With 'Stop at collision' enabled, SolidWorks halts the drag operation the moment the dragged component makes contact with another component.
Question 7: What is the purpose of the 'Physical Dynamics' option in SolidWorks assembly dragging?
- It applies gravity to all components in the assembly
- It allows dragged components to push other components using contact forces (Correct answer)
- It enables full FEA analysis during drag
- It calculates mass properties during motion
Correct answer: It allows dragged components to push other components using contact forces
Physical Dynamics causes components to push, rotate, and interact with each other during manual dragging, simulating real contact dynamics.
