How might we create the best possible solution to a problem? - correct answer.
Engineers try to think "outside the box" in order to solve new problems or find ways to
improve current solutions.
What is the most effective way to generate potential solutions to a problem? How many
alternate solutions should you generate? - correct answer. Brainstorming with a
group, research and testing possible solutions
What is an engineer? What types of work do engineers do? - correct answer.
Engineering is the application of mathematics and scientific principles to better or
improve life.An engineer is a person who is trained in and uses technological and
scientific knowledge to solve practical problems. Research, Develop, Design,
Supervise, Manage, Production and Construction,operations,plant management, and
sales
Why Keep an Engineering Notebook? - correct answer. An engineering notebook is
recognized as a legal document that is used in patent activities to...
Prove the origin of an idea that led to a solution
Prove when events or ideas occurred
Prove diligence in turning the idea into a solution
Prove when an idea became a working solution ("reduced to practice")
What are the 4 best Practices for the Engineering Notebook? - correct answer. Be
Neat,
be Accurate,
be Legible,
be Thorough
,Explain the concept of proportion. - correct answer. Paying close attention to the
underlying basic shapes and the relative proportions of various features of the object
will allow you to more accurately reflect the true shapes and proportions of the object in
your sketch
Why would the ability to create realistic sketches make a person a more competent
designer - correct answer. Representing existing objects and new ideas with sketches
can make the design process more effective and efficient and greatly enhance the
ability of others to understand your ideas.Allows them to communicate their ideas more
clearly.
What is the purpose of sketching your ideas? - correct answer. Sketches provide a
means through which one can quickly and clearly communicate ideas
Define and differentiate invention and innovation. - correct answer. Invention: A new
product, system, or process that has never existed before, created by study and
experimentation.
Innovation: An improvement of an existing technological product, system, or method of
doing something.
Brainstorm - correct answer. A group technique for solving problems, generating
ideas, stimulating creative thinking, etc. by unrestrained spontaneous participation in
discussion
Constrait - correct answer. 1. A limit to a design process. Constraints may be such
things as appearance, funding, space, materials, and human capabilities. 2. A limitation
or restriction.
Design - correct answer. . An iterative decision-making process that produces plans
by which resources are converted into products or systems that meet human needs and
wants or solve problems. 2. A plan or drawing produced to show the look and function
or workings of something before it is built or made. 3. A decorative pattern.
A Design Brief - correct answer. A written plan that identifies a problem to be solved,
its criteria, and its constraints. The design brief is used to encourage thinking of all
aspects of a problem before attempting a solution.
Design Statement - correct answer. A part of a design brief that challenges the
designer, describes what a design solution should do without describing how to solve
the problem, and identifies the degree to which the solution must be executed.
Engineering Notebook - correct answer. An engineering notebook is a book in which
an engineer will formally document, in chronological order, all of his/her work that is
associated with a specific design project.
, Prototype - correct answer. A full-scale working model used to test a design concept
by making actual observations and necessary adjustments.
Research - correct answer. The systematic study of materials and sources in order to
establish facts and reach new conclusions.
Order of Design Process - correct answer. Define Problem
Generate Concepts
Develop a Solution
Construct and test Prototype
Evaluate Solution
Present Solution
Read through the Engineering Disciplines Power Point and write Each Engineering
Field mentioned and one sentence describing what that Engineering Field does. -
correct answer. Chemical Engineering, Civil and Construction Engineering, Electrical
and Electronics Engineering, Mechanical Engineering, Aeronautical Engineering,
Agricultural Engineering, Architectural Engineering, Automotive Engineering, Biomedical
Engineering, Computer Engineering, Industrial Engineering, Manufacturing Engineering
Center Line - correct answer. A line which defines the center of arcs, circles, or
symmetrical parts
Extension Line - correct answer. Line which represents where a dimension starts and
stops.
Dimension Line - correct answer. A line which represents distance
Object Line - correct answer. A heavy solid line used on a drawing to represent the
outline of an object.
Construction Line - correct answer. Line lightly drawn lines to guide drawing other
lines and shapes.
Hidden Line - correct answer. A line type that represents an edge that is not directly
visible
Orthographic Projection - correct answer. A method of representing three-dimensional
objects on a plane having only length and breadth. Also referred to as Right Angle
Projection
Multi-View Drawing - correct answer. A drawing which contains views of an object
projected onto two or more orthographic planes.
Oblique Sketch - correct answer. A form of pictorial in which an object is represented
as true width and height, but the depth can be any size and drawn at any angle.
