Dimensions

Three basic tolerances that occur most often on working drawings are....

• limit dimensions, unilateral, and bilateral dimensions

• limit dimensions, unilateral, and bilateral tolerances.

• unilateral, radius, and bilateral tolerances.

• radius, arch, and bilateral tolerances.

Engineering tolerance is the permissible limit or limits of variation in several areas, choose the one that does not fit:

• measured value or physical property of a material, manufactured object, system, or service

• A physical dimension

• A chemical with in an in particular composition

• in mechanical engineering the space between a bolt and a nut or a hole, etc.

Dimensions should reflect actual size of the object, not the scaled size.

• False

• True

• situational

• Stod

In general a circle is dimensioned by its ______________, and an arc is dimensioned by its ____________.

• circumference/radius

• diameter/circumference

• radius/diameter

• diameter/radius

it is ok a dimension guideline to include chain dimensions that add up to a given overall dimension.

• True

• False

• Orange

Include overall dimension in the three principle directions

• width, height, and depth

• width, height, and length

• length, height, and depth

• width, length, and depth

Which view has the leader line added properly and therefore is dimensioned correctly?

• The image on the left

• the image on the top right

• the image on the bottom right

• the image on the bottom left

Which component is incorrect?

• the extension lines

• dimension text

• dimension line

• arrow head

• they are all correct

Dimensions are placed so that they can be read from the bottom of the drawing sheet. This method is commonly used in mechanical drafting

• aligned

• baseline

• unidirectional

• datem countered

The image represents a common form on linear dimensioning known as.....

• Datum

• Chain

• 3-d dimensional analysis

• iso dim
