- Hacksaw
- Pencil sharpener
-
What physical aspect of a design does a scale model primarily check?
- Material cost
- Electrical circuit
- Chemical composition
- Spatial fit
-
What is the correct next step if a 3-D model is found to be the wrong size?
- Modify and retest
- Discard the project
- Sell the prototype
- Ignore the flaw
-
What is the primary benefit of creating a 3-D model before final manufacturing?
- Guaranteeing full patents
- Removing material waste
- Identifying design flaws
- Eliminating all costs
-
What is the main purpose of using a template in manufacturing?
- Mixing liquid polymers
- Repeated shape marking
