Question 1

There are two basic types of tubing: ____.
A) standard and thinwall
B) standard and extra strong
C) strong and thinwall
D) normal and thinwall

Accepted Answer

Standard and thinwall are the two basic types of tubing, with "standard" referring to the typical thickness and durability for general purposes, and "thinwall" indicating a thinner, lighter variant often used where weight or material savings are important.

Question 2

Nominal sizes for the three basic types of pipes are determined by the ____________________ diameter except when the diameter exceeds 12 inches.

Accepted Answer

inside

Question 3

The partial circles or holes in back of the openings of a standard sheet metal gage are ____.
A) for clearance purposes only
B) to measure clearances
C) to measure the thickness of sheet or plate, or the diameters of wire
D) to determine the type of steel

Accepted Answer

A

Question 4

Sheet thickness may be given as a fraction of an inch (usually as a decimal fraction) or as a ____ number.
A) gage
B) sheet
C) plate
D) band

Accepted Answer

Sheet thickness is commonly measured in gauges, with the higher gauge number indicating a thinner sheet.

Question 5

The openings along the circumference of a standard sheet metal gage are used ____.
A) for clearance purposes only
B) to measure clearances
C) to measure the thickness of sheet or plate, or the diameters of wire
D) to determine the type of steel

Accepted Answer

The openings are used to measure the thickness of sheet or plate, or the diameters of wire, through use of a gauge.

Question 6

Wide-flange beams are identified by the letter "____."
A) I
B) M
C) S
D) W

Accepted Answer

Wide-flange beams are commonly known as "W" beams or "wide flange I beams", and are identified as such because of their distinctive shape. The letter "W" comes from the fact that these beams are shaped like a capital letter "W" when viewed from the side.

Question 7

____ steels are fairly precise in size and have square corners.
A) Hot-tempered
B) Hot-rolled
C) Cold-tempered
D) Cold-rolled

Accepted Answer

Cold-rolled steels are produced by rolling at room temperature and have a high degree of precision in size and squareness of corners. Hot-rolled steels are rolled at high temperatures and may have rounded edges and less precision in size. Hot-tempered and cold-tempered steels refer to the process of heating and cooling to increase or decrease hardness, but do not necessarily affect the precision of size and corners.

Question 8

When specifying certain pipe sizes, schedule numbers may be used in place of standard, extra strong, or double extra strong designations.

Accepted Answer

This is true. Schedule numbers are used to indicate the wall thickness and pressure rating of a pipe, instead of using the traditional designations of standard, extra strong, or double extra strong.

Question 9

There are only a few types and styles of structural metal shapes used in the welding industry.

Accepted Answer

There are actually many types and styles of structural metal shapes used in the welding industry, including beams, channels, angles, tubes, and plates, among others.

Question 10

Miscellaneous beams are identified by the letter "____."
A) I
B) M
C) S
D) W

Accepted Answer

Miscellaneous beams are identified by the letter "M".

Question 11

Bearing pile beams are identified by the letters "____________________."

Accepted Answer

The answer of Bearing pile beams are identified by the...

Question 12

Sheet metal is 3/16" or ____________________(less/more) in thickness.

Accepted Answer

The answer of Sheet metal is 3/16" or ____________________(less/more) in...

Question 13

There are four basic types of pipes.

Accepted Answer

There are various types of pipes used in different industries and applications, such as steel pipes, copper pipes, PVC pipes, etc. Therefore, there are more than four basic types of pipes.

Question 14

____ varieties of steel are slightly oversize and have slightly rounded corners.
A) Hot-tempered
B) Hot-rolled
C) Cold-tempered
D) Cold-rolled

Accepted Answer

Hot-rolled steel varieties are slightly oversize and have slightly rounded corners due to the steel expanding and contracting during the cooling process after being heated to high temperatures.

Question 15

The most commonly used gage is the ____.
A) American Wire Gage
B) Brown and Sharpe Wire Gage
C) Birmingham Wire Gage
D) Manufacturer's Standard Gage for Sheet Steel

Accepted Answer

The answer of The most commonly used gage is the...

Question 16

Standard beams (or I-beams) are identified by the letter "____."
A) I
B) M
C) S
D) W

Accepted Answer

Standard beams, also known as I-beams, are identified by the letter "S" in structural engineering.

Question 17

Nominal sizes are an actual size.

Accepted Answer

Nominal sizes are approximate sizes that are used as labels or descriptions for convenience. They are not the actual or precise size of an object. For example, a 2x4 board is labeled as such, but its actual dimensions are 1.5 inches x 3.5 inches.

Question 18

The ____________________ specification is given in pounds per linear foot.

Accepted Answer

The answer of The ____________________ specification is given in pounds...

Question 19

Sizes listed for many structural shapes are only ____________________ sizes.

Accepted Answer

The answer of Sizes listed for many structural shapes are...

Question 20

Plate thickness is given as a common fraction of an inch.

Accepted Answer

Plate thickness is commonly given in fractions of an inch, such as 1/8 inch, 1/4 inch, or 3/16 inch.
