What is the first step in the Engineering Design Process?
State a hypothesis
Determine variables
Define a problem
Research the problem
At what stage in the Engineering Design Process should you write a Design Brief?
After the problem has been defined, before a solution has been determined
After a prototype has been designed, built, and tested
Just before communicating the final solution (product) to the public
While you're developing a working model
What is the purpose of using a Decision Matrix?
To represent the technical information necessary to produce a product.
To help you systematically evaluate and compare multiple design choices by developing an overall rating for each choice.
To encourage thinking through all aspects of a problem before attempting a solution.
To prove that your problem is valid and justified.
What does the term "iterative" mean?
A process that repeats a series of steps over and over until the desired outcome is obtained.
The occurrence of the same letter or sound at the beginning of adjacent or closely connected words.
A tool used to compare conceptual design solutions against one another, using specific criteria.
A representation of the designed object, process, or system that functions according to the design.
Which term describes this list of things needed for a design to be successful? (the load capacity, the durability, and the aesthetics)

dimensioning
setting constraints
Which of the following is a fully constrained sketch?
A: (Diagram of a quadrilateral with two dimensions labeled 2)
B: (Diagram of two concentric circles, one dimension labeled Ø2.353)
C: (Diagram of a circle and a line with dimensions Ø2, 3, and 40°)
D: (Diagram of two circles with no dimensions)
Which 2D shape on the left would be used to make the 3D shape on the right?
(Square)
(U-shaped figure)
Assuming that the density of water is approximately 1 g/mL, what can you infer about materials with a higher density? A lower density? Mark only one oval.
Materials with density less than 1 g/mL will FLOAT and materials with density greater than water will SINK
Materials with density less than 1 g/mL will SINK and materials with density greater than water will FLOAT
Which part of the caliper is used to measure the internal diameter of an object?
internal jaws
depth blade
thumbwheel
external jaws
What is the main function of the caliper lock on a dial caliper?
To measure depth
To secure the jaws in place for consistent measurement
To reset the scale to zero
To rotate the dial
Which step comes immediately after defining the problem in the Engineering Design Process?
Communicating results
Developing a prototype
Researching the problem
Testing the solution
A group of parts that are connected and form one unit.
