What is Computer Aided Design (CAD)?
Variety of software programs used to design and model parts on the computer, before they are manufactured

Computer Engineering is at the intersection of Computer Science, and what other Engineering field?
Electrical Engineering

Name a project that a mechanical engineer would work on.
Answers could vary

What does an engineer do?
Invent, design, develop, menufacture, and test products and services to improve people's lives.

What is innovation, when it comes to engineering design?
The creation of something new through creativity and design

What was the difference between AutoCAD and SolidWorks?
AutoCAD - 2D
SolidWorks - 3D
200
What is electricity?
Energy created by the movement of electrons

There are 6 simple machines in mechanics. Name one of them.
Inclined plane, wedge, screw, lever, pulley, wheel and axle

What is a technologist?
Someone who specializes in high-level technology.

How is the engineering design cycle different from the scientific method?
Scientific method is focused on answering a question. You complete the process once per question. The engineering design cycle is focuses on creating a product. It is iterative, and can repeat itself multiple times throughout the creation of one design.

In CAD, what does the Object Snap command do?
Allows you to add objects or draw from certain properties of an existing object, such as endpoint, midpoint, tangent, center, intersection, etc
300
In circuits, what is the name for this component:
Resistor
300
Describe the relationship between speed and torque.
As speed increases, torque decreases
400
How are scientists and engineers different?
Scientists perform research and ask why often for the sake of better understanding or more knowledge. They use the scientific method to go about answering questions about why something happens or how something works.
Engineers always have an end goal in mind - they research, design, and build because they are trying to solve a problem. They are more concerned with the application of knowledge rather than knowledge itself. They use the engineering design cycle to design their solutions.

What is the difference between constraints and parameters?
Constraints - limitations on your design (The design must...cost less than $100...fit within an 18" cube...)
Parameters - aspects of your design that you aim to achieve (The design should...last 4 years before needing repair work...be able to withstand pressure at a depth of 100 meters...)
Parameters - aspects of your design that you aim to achieve (The design should...last 4 years before needing repair work...be able to withstand pressure at a depth of 100 meters...)

In CAD, what does the Fillet command do?
Rounds corners and edges

In circuits, what is the name for this component:
Potentiometer

What are the type of gears used in automatic transmission systems in cars?
Planetary gears

ABET accredidation is more important for some fields of engineering than others. Name an engineering field for which it is important, and state why it is important.
Important for professional engineering careers, such as Mechanical, Electrical, Chemical, Civil, Aerospace. It is important because it is a requirement for the Professional Engineering License that the engineer graduate from an accredited program, otherwise their apprenticeship training must last 8 years instead of 4 years.

There are 5 steps in the engineering design cycle. Name them.
Ask, Imagine, Plan, Create, Improve

In CAD, what does the Explode command do?
Separates a shape into its individual parts
500
What is electromagnetism, and how does it relate to motors and generators?
Electromagnetism is the relationship between magnetic fields and electricity. Motors work by rotating a magnet in response to electricity, causing the motor to spin. Generators are the opposite - they rotate a magnet to create electricty.

List Newton's 3 Laws of Motion.
1st - Inertia (an object at rest will stay at rest...)
2nd - F=MA
3rd - For every action there is an equal and opposite reaction
