Geometric Constraints

A student is developing a grabbing device for people who use wheelchairs. The device needs to meet two criteria: it must be able to reach up to 1 meter away and it must be able to pick up items that are 10 cm wide. She develops a model and tests it to determine if it meets the criteria. Which of the following scenarios would test that the grabber can pick up items that are 10 cm wide?

Which of the following geometric constraints is used to ensure that two lines remain parallel in a mechanical design?

• Coincident

• Concentric

• Parallel

• Perpendicular

In the context of geometric constraints, what does the term 'tangent' refer to?

• A line that intersects a circle at two points

• A line that intersects a circle at exactly one point

• A line that is perpendicular to a circle

• A line that is parallel to a circle

Which geometric constraint would you apply to ensure two circles share the same center point?

• Concentric

• Coincident

• Tangent

• Parallel

What is the primary purpose of applying geometric constraints in computer-aided design (CAD)?

• To enhance the visual appearance of the design

• To ensure dimensional accuracy and relationships

• To increase the file size of the design

• To reduce the number of design elements

In a CAD model, which constraint would you use to keep a line at a fixed angle to another line?

• Parallel

• Perpendicular

• Angular

• Tangent

Which of the following is NOT a geometric constraint?

• Horizontal

• Vertical

• Symmetric

• Color

How does a 'coincident' constraint function in a geometric model?

• It keeps two points together

• It keeps two lines parallel

• It keeps two circles concentric

• It keeps two lines perpendicular

What geometric constraint would you use to ensure a rectangle remains a square?

• Equal

• Symmetric

• Tangent

• Concentric
