100
A clear and concise identification and description of the design problem or opportunity.
What is a problem statement?
100
What is an isometric view of a cube?
100
A measuring instrument having two adjustable jaws typically used to measure diameter or thickness.
What is a dial caliper?
100
Adhesives, fasteners, joinery, threads and snap-fits.
What are commonly used joint types?
100
A problem solving principle that states the simplest solution is often the best solution.
What is Occam's Razor?
200
The step in the engineering design process is where we create a working model of our design.
What is the 4th step of the design process: construct and test prototype?
200
Show the visible edges of the object and components, including those exposed by the imaginary cut.
What are object lines?
200
1. Zero the calipers. Bring the external measuring faces together and check that the dial caliper measures zero.
2. Adjust the dial reading using the dial adjustment screw, if necessary.
What steps are needed to calibrate a dial caliper?
200
Identical components that can be substituted for one another, particularly important in the history of manufacturing.
What are interchangeable parts?
200
The difference between the upper and lower limits.
What is tolerance?
300
A written plan that identifies a problem. This document is used to encourage thinking through all aspects of a solution.
What is a design brief?
300
A view that looks inside an object to show interior details that cannot be clearly described on orthographic projections.
What is a cross section?
300
In measurement, this is one-half of the smallest unit of measure (increment) on a device.
What is greatest possible error of measurement?
300
Moves an element sideways.
What is translate?
300
Some degree of this will always exist, and it is unavoidable.
What is variation?
400
A tool used in the second step 2 of the engineering design process. This tool is used to compare conceptual designs using a specific criteria.
What is the decision matrix?
400
- 3D (three sides are shown)
- All principal dimensions (width, depth, and height) are represented in true proportion
- 30 degrees from the horizontal lines
- All height lines are vertical
What are the characteristics of an isometric sketch?
400
The acceptable amount of dimensional variation that will still allow an object to function correctly.
What is tolerance?
400
The point where a joint is applied and the point about which any motion occurs.
What is joint origin?
400
Interchangeable parts can be used.
What is one advantage of using tolerances?
500
The design process is _________. Meaning the path from identifying a problem to presenting a solution is rarely straightforward. Designers must evaluate, reflect, redefine, and redesign throughout the process. It is common to repeat steps of the design process several times before an optimal solution is found.
What is iterative?
500
- Shows the longest dimension
- Shows the best shape and characteristic contours
- Hides the fewest (hidden) edges and features
- Displays the most stable and natural position
What are the guidelines for selecting a front view? or What is the front of an object?
500
Similar to the fractions you used on the ruler, identify the whole number on the measurement bar using this.
What is the scale's reference edge?
500
Basic degrees of freedom or (DOF)
What is movement along the x, y and z axis?
500
Requires quality control and precise manufacturing.
What is small tolerances?
