Deck 11: Dimensions and Tolerances

Question 1

Lengths, widths, or thicknesses are specified using:

A)Unidirectional dimensions
B)Location dimensions
C)Size dimensions

Answer 1

C

Question 2

In the aligned method of dimensioning, all dimensions are read from the bottom of the page.

Answer 2

False

Question 3

Fractional tolerances are most likely to be found on:

A)Precisely machined parts
B)Where close tolerances are required
C)Castings and forgings

Answer 3

C

Question 4

Dimensions should be placed between views where possible.

Question 5

Various views on a drawing show the shape of an object. The sizes of an object and its features are shown by dimensions.

Question 6

ASME standards recommend:

A)The aligned method of dimensioning
B)Unidirectional dimensions

Question 7

Lines used in dimensioning are:

A)Fractional, decimal, and angular lines
B)Extension, dimension, and leader lines
C)Unilateral and bilateral lines
D)Unidirectional and aligned lines

Question 8

A tolerance that is given as both a plus and a minus dimension is:

A)A bilateral tolerance
B)A unilateral tolerance

Question 9

Unilateral tolerances are always "tighter" than bilateral tolerances.

Question 10

Dimensions, such as the thickness of an object, should be shown several places on a drawing.

Question 11

Limits of accuracy, within which dimensions must fall, are specified by:

A)Fractional dimensions
B)Location dimensions
C)Unidirectional dimension
D)Tolerances
