Deck 2: Drafting Equipment, Media, and Reproduction Methods

Question 1

According to the American Society of Mechanical Engineers document ASME Y14.5-2009, Dimensioning and Tolerancing, what is the commonly used International System of Units (SI) linear unit used on engineering drawings? What is the commonly used U.S. customary linear unit used on engi- neering drawings?

Answer 1

The millimeter (mm) and the decimal inch (IN)

Question 2

The triangular architect's scale contains 11 different scales. Describe how these scales are calibrated.

Answer 2

. On ten of the scales, each inch represents a specific increment of feet. Each foot is subdivided into multiples of 12 parts to represent inches and fractions of an inch. The degree of precision depends on the specific scale. The eleventh scale is the full scale with a 16 in the margin. The 16 means that each inch is divided into 16 parts, and each part is equal to

Question 3

Why are drawings scaled?

Answer 3

Drawings are scaled so the objects represented can be illustrated clearly on standard sizes of paper.

Question 4

What does the zoning location D4 mean?

Question 5

Describe vellum.

Question 6

What name describes traditional drafting practice using pencil or ink on a medium such as paper or polyester film with the support of drafting instruments and equipment?

Question 7

Give the dimensions of an ASME B-size sheet.

Question 8

Describe the border of a sheet.

Question 9

How do you specify a half scale when using inches?

Question 10

How do you specify a full scale when using inches?

Question 11

Define the instrument called a scale.

Question 12

Name the ASME standards that recommend sheet sizes and format.

Question 13

How are the civil engineer's scales calibrated?

Question 14

Give the dimensions of an ASME A3-size sheet.

Question 15

Define zoning.

Question 16

Define brainstorming.

Question 17

What has replaced the traditional drafting practice using pencil or ink on a medium such as paper or polyester film with the support of drafting instruments and equipment?

Question 18

How is the 50 scale on the mechanical engineer's scale calibrated?

Question 19

Identify the basic function of a scale.

Question 20

State the general note that all engineering drawings shall have as related the linear units used on the drawing.

Question 21

When is the zoning compartment of the revision history block used? What is its purpose?

Question 22

Define microfilm.

Question 23

Where do the ASME standards recommend placing the title block?

Question 24

What is a continuation sheet title block? When is it used?

Question 25

What does an application block include?

Question 26

Identify the purpose of the sheet size designation in the title block and give an example.

Question 27

Give at least two examples of how the scale is identified in the title block and what is specified if the drawing has no scale.

Question 28

Describe the function of the revision status of sheets block and when it is used.

Question 29

Describe the revision history block and identify its location.

Question 30

Give another name for photocopy printers when used in an engineering environment, and briefly describe their function.

Question 31

Give the purpose of the angle of projection block.

Question 32

Give the purpose of the revision block in the title block and identify (1) what is used for an original drawing and (2) what is used the first time the drawing is hanged.

Question 33

Give the purpose of the sheet block in the title block and show how two multiple sheets are identified.

Question 34

Explain how optimum efficiency of design and manufactur- ing methods is achieved without producing a single paper copy of a drawing of a part.

Question 35

Identify the purpose of the dimensioning and tolerancing block.
