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. All datum simulators must be at least ___ times better in quality than the tolerances specified on the drawings to be considered datum simulators






2. In GD&T - ___ of a surface specifies a 3D tolerance zone defined by two contoured surfaces. When a datum reference is not specified - the tolerance controls only the shape of the contour. When datums are specified - the tolerance controls the shape o






3. ___ refers to a fit where there is space between the two mating parts.






4. Baseline dimension is often used for CNC machines that work from a ___ coordinate system






5. Dimension lines als should be at least ___ millimeters from any view - helping to avoid clutter






6. Unless otherwise specified - all dimensions are applicable at ___ degrees celsius. compensation may be made for measurements made at other temperatures..






7. in some ways - symmetry and concentricity are very similar. The main difference is that the former is typically concerned with the position of a center plane relative to an axis or a center plane of a datum feature.






8. All dimensions and tolerances apply in a free state condition. this principle does not apply to ___ parts






9. In DG&T - the ___ reference frame is a theoretical system made up of three mutually perpendicular planes established by real features on the object.






10. When you dimension holes - you string the symbols together in ___






11. Datums are always required for ___






12. Engineering drawings require the use of single stroke ___ lettering






13. Datums are not allowed for v






14. Which type of english fit is inteded where accuracy of location is of prime importance and where parts require rigidity and alignment with no special requirement for bore pressure?






15. ___ is a 2D control similar to circulatirty or roundness. the main difference is that it controls a surface relative to a datum axis.






16. ___ are used to direct a dimension - note - or symbol to the intended place on a drawing.






17. A ___ is typically a planar surface or a feature where the normal vectors point in the same direction






18. ___ holes are used for applications with flat head and oval head screws






19. ___ is the difference between the maximum material limits of mating parts






20. In ___ dimensioning - features are dimensioned relative to one another






21. There are standards for specifying particular types of geometry. for example - circles are typically dimensioned as ___ - and arcs are dimensioned as radii






22. ___ dimensioning usually yields the largest accumulation of tolerance between features.






23. A small triangle at the end of a dimension liens and leaders that indicates the direction and extent of a dimension is called a ___






24. When profile tolerances are equally distributed about the perfect geometry of the features - this is referred to as a ___ distribution.






25. Which type of metric fit is suitable for parts that can be highly stressed or for shrink fits where the heavy pressure forces required are impractical?






26. A numerical value expressed in appropriate units of measure and used to define the size - location - geometric characteristic - - or surface texture of a aprt or part feature is a ___






27. ___ tolerances are tolerances where the deviation is divided in some way above and below the basic size of the dimension.






28. ___ fits are typically associated with selective assembly






29. The accepted national standard in the united states for dimension and tolerancing is...






30. A good rule of thumb to follow when dimensioning is to dimension only visible or ___ lines






31. A thin - dark - solid lien extending from a point on an object and perpendicular to a dimension line is called an ___






32. The counterpart of MMC is the ___ - which is the condition in which a feature of size contains the minimum amount of material within the stated limits of size






33. ___ holes are standard machined holes that are used to accept fillister head and hex sockets head screws






34. In ___ dimensioning - all of the dimensions in a given direction originate from a base or datum






35. For machined parts - the amount of variation - or ___ - might be relatively small






36. In GD&T - the ___ (MMC) modifier allows the size of the zone to change if the size of the hole changes






37. The main focus of GD&T is the ___ frame which contains the geometric characteristic symbol - the geometric tolerance - and the relative datums.






38. when the inside dimensions are more important or more critical than the overall dimension - the overall dimension should be identified as a ___ dimension






39. ___ tolerances are for individual features and are not related to any datums. This group of geometric tolerances includes straightness - flatness - circularity - and cylindricity






40. ___ are beveled or angled edges that typically appear on the ends of shafts or fasteners. They are dimensioned by giving a length from the end of the part and an angle or by specifying two distances






41. A ___ is a cylindrical or spherical surface or a set of two opposed elements or opposed parallel surfaces associated with a size dimension






42. Most drawings conform to the International System of Units (SI) which is metric and uses the ____ as the standard unit; or they conform to US customary unites with standard unit of the decimal inch






43. ___ dimensioning an tolerancing is a 4d mathematical system that allows a designer to describe the form - orientation - and location of features on a part within precise tolerance zones.






44. ___ notes typically appear in the lower right hand corner of a drawing and apply to the whole drawing






45. Arcs are dimensioned as radii using the ___ symbol - which is shown preceding the dimension value.






46. A good analogy of the ___ control is a stack of pennies. this tolerance would control how round each penny is but not the straightness of the whole stack






47. A __ line - along with its arrowheads - shows the direction and extent of a dimension






48. Each dimension shall have a ___ - except for those dimensions specifically identified as reference - maximum - minimum - or stock
