The Design Process
This is defined as a systematic problem-solving strategy used to develop solutions to solve a problem or satisfy human needs and wants.
What is the Design Process?
This line type represents an edge that is not directly visible because it is behind or beneath another surface.
What is a hidden line?
This measurement concept describes how close a recorded value is to the true, actual value
What is accuracy?
Expressed as a formula, this is how physical density is determined using mass and volume.
What is D = M/V (Density equals Mass divided by Volume)?
This is a tool utilized for systematically ranking design alternatives according to a predetermined set of criteria.
What is a decision matrix?
A team of students is actively brainstorming different ways to solve a problem. They are currently working in this specific step of the design process.
What is Generate Concepts?
These are the three standard views traditionally included in a standard multiview drawing
What are the Top, Front, and Right Side views?
This statistics and measurement term refers to the degree of repeatability in a set of measurements.
What is precision?
Constant, non-numerical relationships between geometric parts—such as parallelism, perpendicularity, and concentricity—are known as this.
What are geometric constraints?
These are views of an object projected onto two or more orthographic planes to accurately capture its features.
What are multiview drawings?
This written plan explicitly identifies a problem to be solved, its criteria, and its constraints to encourage thinking of all aspects before attempting a solution.
What is a Design Brief?
In an isometric sketch, all three primary drawing axes form this exact, equal angle measure with the plane of projection.
What is 120° (or 120 degrees)?
If a standard dial caliper reads 2.0 inches on the main blade and the dial needle points directly to 45, this is the total measurement value.
What is 2.045 inches?
This term refers to the total permissible variation allowed in a size or location dimension.
What is tolerance?
Also referred to as Right Angle Projection, this is a method of representing three-dimensional objects on a plane having only length and breadth.
What is orthographic projection?
While criteria are the requirements or desires for a design, these represent the rigid limitations such as time, money, and materials.
What are constraints?
These are thin lines that serve strictly as guides while sketching or drawing
What are construction lines?
These are the calculated mean and median values, respectively, for the dataset: 12, 15, 12, 18, 20.
What are 15.4 (mean) and 15 (median)?
If a wooden block has a mass of 150 grams and a total volume of 200 cubic centimeters, this is its calculated density.
What is 0.75 g/cm³?
This type of drawing shows the interior of an object as if it were cut in half, utilizing distinct, thin lines to show the material through which the cut was made.
What are a sectional view (section lines)?
This is the specific step of the design process where an engineer would create a technical working drawing.
What is Develop a Solution?
This is a form of pictorial sketch in which vanishing points are used to provide the depth and distortion that is seen with the human eye
What is a perspective sketch?
Three measurements (5.48, 5.49, and 5.48) are taken of a part whose true value is 5.75. This statement correctly describes the precision and accuracy of these data points.
What is precise, but not accurate? (They are precise because the values are close together, but inaccurate because they are far from the true value)
This is the approximate total volume of a cylinder that features a radius of 2 inches and a height of 5 inches.
What is 62.8 cubic inches?
Volume= pi (r^2) h = ~3.14 * 4 * 5 = 62.8 cubic inches
This is a time and activity bar chart used by engineers for planning, managing, and controlling major programs that have a distinct beginning and end.
What is a Gantt chart?
