Engineering and Design - Unit 4: Quiz 1. Introduction To Reverse Engineering

1. a detailed diagram that shows all parts of an object removed from their base structure and connected by dotted lines to show where the components should fit together. 2. putting a device to use to find out how well it works. 3. having no or imperfect symmetry but still appearing balanced.

1. Glenn is deconstructing a computer to replace worn parts so that its function can be improved. 2. Leslie has just created a new operating system that will allow engineers to transform their sketches into three-dimensional images. 3. Sean has been hired to create a new computer monitor, keyboard, and electrical circuit board.

1. components 2. software 3. hardware

1. An engineer is using a concept generation table to analyze the structure and function of each parameter of a newly designed computer. 2. Jonathan is compiling a diagram to graphically represent the different functions a toaster performs, along with inputs and outputs. 3. As Paige deconstructs a remote-controlled toy, she carefully documents important information by assigning numbers and names to each component.

1. In the functional analysis stage, John begins to break down a product in a step-by-step fashion, documenting each component and function. 2. An engineer is testing how much heat a new material in a barbecue grill can withstand. 3. As Julie completes her deconstruction of a hair dryer, she is sure to include each of the joints, fasteners, and adhesives used in the product.

1. product teardown analysis 2. stress analysis 3. structural analysis

1. Tyrone is able to describe the inside of a microwave by looking at its design elements. He is noting that it is gray, rectangular, and has a rotating tray inside. 2. Carrie is exploring the operations of a microwave by studying each component and how they interact; this way she can learn more about the microwave's purpose and design. She notices that the rotating tray is attached to a piston that turns in a clockwise direction. 3. Connor is gathering information about the organization, materials, and manufacturing methods used to create a microwave. He notes how the microwave was assembled and then researches the manufacturing plant where it was assembled.

Explain the function of a black box system model.

A black-box model, or more specifically a black box financial model, is a catch-all term used to describe a computer program designed to transform various data into useful investment strategies.

Which of the following describes boundaries?

Boundaries are primarily used to indicate which functions a product will perform as opposed to the functions that a user will perform.

Which option identifies the conclusion Jack can draw from the reverse engineering experience in the following scenario? Jack has dismantled a lawn mower; in his product teardown chart he has noted that the pistons have experienced extreme wear and will need to be replaced soon.

Future enhancements may explore different materials or shapes in order to reduce wear.

Which of the following explains why engineers are concerned with aesthetics?

Many users are unconsciously attracted to objects by way of aesthetics.

Which of the following is important when engineers review a function structure diagram?

The engineer must make sure all of the subsystems are broken down to the smallest level so that no simpler functions can be described.

Which of the following explains how engineers define the purpose of an object?

They base the purpose of an object on the design parameters that are given and needed.

Which option identifies the step essential to putting the weed whacker back together in the following scenario? Kristin is taking apart a weed whacker to study its fuel tank. She is attempting to create a new weed whacker that is more fuel-efficient.

a product teardown chart

Which of the following describes how most products work?

as systems

Which option identifies the step of reverse engineering described in the following scenario? Jonathan is conducting reverse engineering on a toy that was on the market around 25 years ago. As he examines the toy, he creates questions that he will need to find answers to; these include the target age of the product, the target gender of the product, and the intended use of the product.

audience analysis

Which term is defined as taking something apart?

deconstruction

A product breakdown chart documents the internal operations of a product.

false

After examining a morphological matrix, an engineer determines the best possible version to the product.

false

An engineer must complete a micro properties analysis to determine the amount of materials needed to manufacture each item.

Which option identifies the building design described in the following scenario? Jeremy has just designed a building for the city of Richmond, Virginia. He has received an award for the aesthetics of the building. The building is not symmetrical, but it still appears balanced.

informal balance

In the context of design, element is defined as which of the following?

part of a design that can be described

Which of the following processes do engineers use to analyze a product that is already available?

reverse engineering

A matrix identifies components that share similar functions.

true

Which of the following correctly identifies what must be paired with an educated guess or hypothesis in reverse engineering?

valid reasoning

Which option identifies the stage of reverse engineering described in the following scenario? Kyle has been hired by an engineering firm to create a fuel tank that will be much more efficient than the current fuel tanks on the market. He has just opened a fuel tank from inside a car engine and is observing the mechanisms inside.
