What step in the design process would a Design Brief be created?

\

Step 4.

Where do Designers and Engineers record their daily work for legal and archival reasons?

\

In their design notebook.

Describe the difference between Oblique and Isometric sketches.

An oblique sketch has more focus on the front side of an object or the face. Isometric Sketch focuses on the edge of an object

What is Tonal shading?

Tonal shading refers to the lightness or. darkness of an object. It is done by setting down various strengths of shading to demonstrate where an object is affected by the light and shadows.

\

What is the conversion between inches and millimeters?

1 to 25.4

Be able to read a dial caliper.

Look at the ruler part for the first two digits (example: 1.2 inches), then look at the dial for the third digit (example: 1.23)

How do you find the mean, median, and mode of a set of numbers?

\

The mean is the average, add up all the numbers and divide your result by the number of numbers you added together. The median is the middle, add the largest and the smallest numbers and divide by two to get the middle. The mode is the most common number out of any given set of numbers, find this by tallying how many times each number in a set appears, the one with the most marks is the mode, or most common.

\

What is the difference between a mockup and a prototype?

Mockup: A mockup is a high-fidelity render of your design that showcases how the finished product will look. Prototype: A prototype is an early model of a product that focuses on functionality and gives your stakeholders a taste of the final version.

\

Define Collinear, Perpendicular, Parallel, Concentric, Tangent conditions for geometric constraints.

Collinear: Constraints two or more objects so that they share a common line. Perpendicular: Constraints two objects so that they lie perpendicular (at a 90-degree angle) to each other. Parallel: Constraints two lines so that they extend in the same direction and never intersect. Concentric: Constraints two arcs, circles, or ellipses to the same center point. Tangent: Constraints a curve and another object so that they touch at a single point but never cross each other.

\

On a hole callout (Dimensions of a hole) what symbol is used for countersink and counterbore?

The symbol for a countersink hole is V while the symbol for a counterbore hole is U.

How do you find the area of a triangle?

Base times height divided by two.

\

What is Datum Dimensioning?

Datum Dimensioning allows for the dimensioning of a linear distance of a collection of objects, relative to a single reference object. The first object chosen is the 'base'. All subsequent objects are relative to this first object.

Why is Datum Dimensioning used over Chain dimensioning?

Datum Dimensioning reduces the small error build up.

How many directions can two components move if they are attached with a planar joint?

Two, back and forth along one plane.

\

What is the difference between a Thru hole and a Blind hole?

A through hole goes all the way through the face, allowing you to see through to the other side. A blind hole however goes a set depth into a face but never breaks the surface, if you were to look through you would be blind or unable to see what was behind the other face.

\

Describe a section view in a dimensioned drawing

A view that shows you the top corner of the object, showing 3 faces instead of 1.

What is a target consumer?

\

The type or age of people that your product is targeted at, and expected to be bought by.

\

List and describe the parts of a design brief.

A design brief is a project management document outlining the specifics of a design project. There's no standard of what to include, but some common points are the design project overview and scope, timelines, target audience information, and budget.

\

What is a hydraulic cylinder?

A hydraulic cylinder is a mechanical actuator that is used to give a unidirectional force through a unidirectional stroke. It has many applications, notably in construction equipment, manufacturing machinery, elevators, and civil engineering.

\

What are the different types of balance? (Visual design principles)

There are five types of balance in graphic design: symmetrical, asymmetrical, radial, mosaic and discordant.

\

Define reverse engineering.

The reproduction of another manufacturer's product following detailed examination of its construction or composition.

\

What is the difference between a Tension Force, a compression Force, and a Torsion Force?

Tension is pulling apart, Compression is pushing together, and Torsion is twisting.

\

How do Engineers simulate the force/stresses on an object using a computer?

Finite element analysis (FEA) is the primary method for simulating stress analysis. It predicts what will happen to an object when subject to physical forces like vibration, heat transfer, mechanical stress, electrostatics, and motion.

\

What factor determines how much chrome plating material will be needed for a given object?

The surface area of the object.

\

What is the difference between innovation and invention?

An invention is a brand new product, an innovation is a change, improvement, or variation of that base product.

\

What is discovered through researching demographic data?

Statistics about things like age, race and sex.

\

What US Government Agency regulates workplace safety?

OSHA

\

What is a Gantt chart?

A chart in which a series of horizontal lines shows the amount of work done or production completed in certain periods of time in relation to the amount planned for those periods.

\

Define Virtual Team:

A virtual team is a group of workers who communicate and work together using digital tools.

\

What is design team consensus?

When everyone on the team comes to an agreement.

\

What is an auxiliary view in a dimensioned\`drawing (finding an example picture will help)?

An auxiliary view is a view which shows the slanted part of the object as it actually is.
