Intro to Engineering Final Exam Review

What is an engineer?

An engineer is a person who is trained in and uses

technological and scientific knowledge to solve practical

problems.

What is the most effective way to generate potential solutions?

Brainstorm

How many potential solutions should be generated?

As many as possible

Why keep an Engineering Notebook?

To organize thoughts and prove origin of an idea in legal situations.

Why would the ability to create realistic sketches make a person a more competent designer?

It allows them to communicate the design more clearly.

What is the purpose of sketching your ideas?

Sketching allows a person to quickly and clearly communicate an idea.

Define and differentiate invention and innovation.

Invention: A new product, system or process never created before

Innovation: An improvement on an existing product, system or process

Define Brainstorm

A group technique to generate concepts, solve problems and stimulate creative thinking

Define Constraint

A limit to a design process

Design

A plan or drawing to show the look or workings of something before it is built

Design Brief

A document stating what the problem entails by describing it, how to solve it (briefly) and the constraints

Design Statement

Describes how to solve the problem

Engineering Notebook

A place for engineers to plan/design/ document their work

Prototype

A full-scale working model used to test a design model

Research

The act of searching for facts or content already in our world

The representation of light and shade on a sketch or drawing is?

Tonal Shading

What type of drawing is used to illustrate product and give presentations?

Pictorial

What type of drawing is used when the product is intended to be manufactured?

Multiview

How can statistical and analyzed

data be used to inform, justify, and validate a

design or process?

Statistical and analyzed data can be used to maintain and control data.

Why engineers generally adhere to a set of dimensioning standards and guidelines?

The part may not fit or function properly if not dimensioned correctly. These delays from not following the standards can cause production delay and/or greater production costs.

Why do designers need to fully dimension a part?

To fully communicate how the part should be made.

What does it mean to over dimension a sketch?

When their is duplicate dimensions for a length.

A graph of vertical bars representing the frequency distribution of a set of data is called.

Histogram

A measure of center in a set of numerical data

Median

A function that represents the distribution of variables as a symmetrical bell-shaped graph.

Normal Distribution

The value the occurs most frequently in a given data set.

Mode

The distance of a value in a population from the mean value of the population.

Deviation

What is Central Tendency?

It is the center of a distribution: Mean, Median or Mode

A full-scale working model used to test a design concept by making actual observations and necessary adjustments.

Prototype

A measuring instrument having two adjustable jaws typically used to measure distance or thickness.

Dial Caliper

How is a geometric constraint different from a numeric constraint in the Inventor program?

A geometric constraint "bonds" two geometric parts together. A numeric constraint constrains an object to a certain measurement or distance.

What 3D CAD functions could be used to create a wire paper clip?

Sweep

What feature would be used to create a 3D representation of a baseball of softball bat that was created on a wood lathe?

Revolve

Arcs and circles are dimensioned in views that ____

Show the arc or circle

Arcs are dimensioned with a ___ to identify the ___; in some cases, a center mark is included.

Leader....Radius

Circles should have a ______ mark and are dimensioned with a ____ to identify the ____.

Center....Leader.....Diameter

What is an offset and how is it used?

Keeping the same shape; it copies it to a smaller or larger scale

What is the difference between a mate and a flush?

Mate: Two surfaces face to face

Flush: Two surfaces side by side or two edges side by side

What constraint would you use to place a pin inside a hole?

Insert Constraint

What is a subassembly? How is it useful in the assembly of a complex product that involves multiple parts?

A subassembly is when some parts of a product are put together, and then those subassembles are put into one total assembly.
