100% VERFIED | ALREADY GRADED A+
What are double lines called - (answer)Tangent Edges
Do dimensions carry uncertainty - (answer)Yes
Definition of Tolerance - (answer)A range of variability for a dimension that will guarantee that
the object will work as intended
Is this part of the ASME Y14.5 Rules: Every feature shall be explicitly and fully dimensioned
leaving nothing for assumption True or False - (answer)True
What is the exception for redundant dimensions - (answer)Reference dimensions shown by either
() or REF
Should the tolerance of a dimension by specified locally or globally - (answer)Can be both
,What are exceptions to the rule: " All dimensions must have tolerances" - (answer)Stock or
Reference dimensions do not require
Dimensions should only suit the mating relationship and not the function - (answer)False,
dimensions should suit both the mating and the function relationship in a way that is ambiguous
in their interpretation
Which method of dimensioning has a higher tolerance: Chain or Baseline - (answer)Chain
What is the "contour rule" - (answer)Dimensions should be applied in the view where the
contour is most visible
Can arcs be dimensioned in diameter - (answer)No, only radius
Should you dimension hidden lines? - (answer)You should not
What materials have a linear dimension - (answer)Stock Materials
,At what temperature are all dimensions applicable unless specified - (answer)Room Temperature
(20 C)
What is the difference between a clearance and interference fit - (answer)A clearance fit has
space and guarantees a free running operation while an interference fit has negative space and
guarantees position
Specify tolerance for a hole basis, LC5 fit for a 1/2 diameter pin hole set. Hole Tol = 0.7
Shaft Tol = 0.4 - (answer)Hole Tol = 0.500 - 0.507
Shaft Tol = 0.500 - 0.496
What is a datum - (answer)A theoretical reference plane where geometric dimensioning refers
from
What is the current standard for dimensioning and tolerancing in the United States? -
(answer)ASME Y14.5
Explain the difference between dimensioning standards for inches and the standards for
millimeters. - (answer)Inches do not contain trailing zero while millimeters do
, When a two-view drawing of a simple rectangular block is given, what dimensions are
necessary? - (answer)Length, Width & Height
Explain the difference between baseline and chain dimensioning. - (answer)Baseline
dimensioning uses an origin point to reference while chain dimensioning dimensions from one
feature to the next
Explain why the dimensions for a constraint-based solid model of a design may be different from
the dimensions that appear on a detail drawing of the part - (answer)Dimensions in a constraint-
based solid model may differ from those in a detail drawing due to design intent versus
manufacturing requirements. Solid models focus on functionality, while detail drawings specify
precise dimensions and tolerances for accurate production. Geometric dimensioning and
tolerancing ensure alignment between design intent and manufacturing specifications.
Describe interchangeable manufacturing - (answer)Interchangeable manufacturing involves
producing parts to standardized dimensions, allowing them to be easily interchanged without
affecting functionality. Two daily-use products relying on this are USB flash drives and light
bulbs.
