G5 Unit 2, Lesson 1-2 Quiz

Which of these is an example of technology? (Lesson 1)

*Hint: Take a look in the book at the definition of technology.

• developing a hypothesis

• formulating a new theory

• a sketch of an engine

• an artificial hip-replacement

Which statement best describes the reason technology changes over time? (Lesson 1)

• People enjoy having new technology.

• Old technology never meets the needs it was designed for.

• People's needs are better met when technology is very complex.

• People find better ways to meet their needs as their knowledge increases.

What is the first step an engineer should take in developing a new technology? (Lesson 1)

• Identify the problem to be solved.

• Test the model of the new machine.

• Design the model for the new machine.

• Evaluate the performance of the machine.

An engineer designed four braces to offer comfort and support for people who have had knee surgery. The table below shows the results from a survey of 100 people who tried the engineer's four prototype braces.

What can the prosthetic designer assume from the information in the table? (Lesson 1)

• Brace A is preferred by a majority of the people surveyed.

• Brace B would most likely keep people from becoming injured again.

• Brace C would be the best choice for comfort and support.

• Brace D is the brace that can most likely be improved by further design.

How is failure part of the design process? (Lesson 1)

• Once a prototype fails, the process has ended.

• Failure is not part of the design process.

• Failure convinces engineers to give up.

• Failure can reveal areas that need improvement.

A designer has been asked to design a computer desk chair that encourages the user to assume good posture and work position. Which is the main responsibility of the designer? (Lesson 2)

*Posture is the position in which someone holds their body when sitting.

• to use new technology in the design

• to make the chair easy to manufacture

• to make the design safe and comfortable

• to be sure that users understand the technology of the chair

Which is the best reason for sketching or drawing a design before constructing it? (Lesson 2)

• Once constructed, a design cannot be changed at all.

• A functioning design is not as interesting as a sketch.

• Certain design improvements can be made more easily in a sketch.

• Sketching reflects the design's function in the real world without error.

A bioengineer is developing a prototype for a prosthetic hand (artificial device to replace a missing or impaired part of the body). The table shows the test results.

Based on the test results, which of the following best describes how to redesign the prototype? (Lesson 2)

• Redesign the prothesis to apply for a patent.

• Redesign the prothesis with more lifelike materials.

• Redesign the prothesis so that it is easy to put on and take off.

• Redesign the prothesis so that the wrist joint has a better range of motion.

Sometimes a new product is test-marketed. A limited amount of the product is released to a group of users. Then the group is observed to see how the product performs. Which step might occur in the design process after a product is test-marketed and before it is mass-produced? (Lesson 2)

test-marketed = test round / mass-produced = produced in large quantities

• The design is detailed in drawings.

• The design is measured and evaluated.

• The product design is copyrighted and patented.

• The product is redesigned based on evidence that is observed and gathered.
