Intro To Engineering Design - 2

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. A CAD modeling method that uses parameters to define the size and geometry of features and to create relationships between features. Changing a parameter value updates all related features of the model at once.






2. The variables by which an object can move. In assemblies - an object floating free in space with no constraints to another object can be moved along three axes of translation and around three axes of rotation. Such a body is said to have six degrees






3. A rounded interior blend between two surfaces. Some uses are to strengthen joining surfaces or to allow a part to be removed from a mold.






4. A line used to show the alternate positions of an object or matching part without interfering with the main drawing.






5. A slot in a shaft to receive a key.






6. A circled number identifying each part shown in an assembly drawing. Also called a ball tag or bubble number.






7. A system of dimensioning which requires all numerals - figures - and notes to be aligned with the dimension lines so that they may be read from the bottom (for horizontal dimensions) and from the right side (for vertical dimensions).






8. The largest and smallest possible boundaries to which a feature may be made as related to the tolerance of the dimension.






9. A type of 3D CAD modeling that represents the volume of an object - not just its lines and surfaces. This allows for analysis of the object's mass properties.






10. Also referred to as the U.S. Customary system. The measuring system based on the foot - second - and pound as units of length - time - and weight or mass.






11. A tolerance in which variation is permitted in both directions from the specified dimension.






12. The amount of overlap that one part has with another when assembled.






13. The designation of the size established for a commercial product.






14. A dimensioning system which requires all numerals - figures - and notes to be lettered horizontally and be read from the bottom of the drawing sheet.






15. An orthographic view of an object using a direction of sight other than one of the six basic views (front - top - right- side - rear - bottom - left- side); used to show a surface that is not parallel to any of the principal view planes.






16. Constant - non - numerical relationships between the parts of a geometric figure. Examples include parallelism - perpendicularity - and concentricity.






17. The smallest size limit of an external feature and the largest size limit of an internal feature.






18. The total permissible variation in a size or location dimension.






19. A graph of vertical bars representing the frequency distribution of a set of data.






20. Lines that are used to represent the material through which a cut is made in order to show an interior sectional view.






21. A shallow recess like a counterbore - used to provide a good bearing surface for a fastener.






22. A tolerance in which variation is permitted in only one direction from the specified dimension.






23. A dimension - usually without a tolerance - used for information purposes only. A reference is a repeat of a given dimension or established from other values shown on a drawing. Reference dimensions are enclosed in ( ) on the drawing.






24. A theoretically exact point - axis - or plane derived from the true geometric counterpart of a specific datum feature. The origin from which the location - or geometric characteristic of a part feature - is established.






25. Also known as point- to- point dimensioning where dimensions are established from one point to the next.






26. 1. A professional engineering organization that is known for setting codes and standards for mechanical devices in the United States. ASME drawing standards are found in the Y-14M publications. 2. The acronym for the American Society of Mechanical En






27. 1. A triangle located round a polygon such as a circle. 2 To draw a figure around another - touching it at points but not cutting it.






28. To draw a figure within another so that their boundaries touch but do not intersect.






29. A rectangular coordinate system created by three mutually perpendicular coordinate axes - commonly labeled X - Y - and Z.






30. 1. A manufacturing process that forces material through a shaped opening. 2. A modeling process that creates a three- dimensional form by defining a closed two- dimensional shape and a length.






31. A slot in a hub or material around a shaft that receives a key.






32. A group of values that is used to analyze the distribution of data.






33. A cylindrical recess around a hole - usually to receive a bolt head or nut.






34. The decimal measuring system based on the meter - liter - and gram as units of length - capacity - and weight or mass.






35. A sketch that shows an object's height - width - and depth in a single view.






36. 1. A private - non - profit organization that coordinates the development and use of voluntary consensus standards in the United States. 2. The acronym for the America National Standards Institute.






37. Lines that are thin and used to connect a specific note to a feature.






38. A part of 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.






39. A dimensioning system where each dimension originates from a common surface - plane - or axis. Also known as baseline dimensioning.






40. 1. For design - the use of a computer to assist in the process of designing a part - circuit - building - etc. 2. For drafting - the use of a computer to assist in the process of creating - storing - retrieving - modifying - plotting - and communicat






41. Where alternate units are displayed within the same dimension (both metric and standard dimensions can shown at the same time).






42. A small angled surface formed between two surfaces.






43. A type of 3D CAD modeling that represents the volume of an object - not just its lines and surfaces. This allows for analysis of the object's mass properties.






44. System of dimensioning in which all dimensions are placed from a datum and not from feature to feature. Also referred to as Datum Dimensioning.






45. A non - governmental global organization whose principal activity is the development of technical standards through consensus.






46. A conical- shaped recess around a hole - often used to receive a tapered screw.






47. A number value - or algebraic equation that is used to control the size or location of a geometric figure.






48. Gradual diminution of width or thickness in an elongated object.






49. The largest size limit of an external feature and the smallest size limit of an internal feature.






50. 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.
