1. SELECT THE NAME OF THIS MATERIAL.

ANGLE IRON

FLAT BAR

HR SOLID

CHANNEL

The correct answer is "ANGLE IRON" because it is the only option listed that matches the material described in the question. The other options, "FLAT BAR," "HR SOLID," and "CHANNEL," do not match the given material.

Explanation

The correct answer is "ANGLE IRON" because it is the only option listed that matches the material described in the question. The other options, "FLAT BAR," "HR SOLID," and "CHANNEL," do not match the given material.

2. WHAT IS THE NAME FOR THIS MATERIAL?

ROUND TUBING

SOLID ROUND

SQUARE TUBING

PIPE

The given material is named "Solid Round" because it is a solid cylindrical shape without any hollow space or opening. It is not a round tubing because it is not hollow, not a square tubing because it is not a square shape, and not a pipe because it is not designed to transport fluid or gas. "Solid Round" accurately describes the material as a solid, cylindrical shape.

Explanation

The given material is named "Solid Round" because it is a solid cylindrical shape without any hollow space or opening. It is not a round tubing because it is not hollow, not a square tubing because it is not a square shape, and not a pipe because it is not designed to transport fluid or gas. "Solid Round" accurately describes the material as a solid, cylindrical shape.

3. TO FIND OUT THE INNER DIMENSION OF ROUND TUBING, YOU TAKE THE OUTSIDE DIMENSION AND SUBTRACT IT BY 2X OF WHAT?

To find out the inner dimension of round tubing, you take the outside dimension and subtract it by twice the wall thickness. This is because the wall thickness on both sides of the tubing contributes to the reduction in inner diameter. Subtracting twice the wall thickness ensures that both sides are accounted for, resulting in the accurate inner dimension of the tubing.

4. THE OUTSIDE DIAMETER OF 3" PIPE IS 3."

True

False

THE OUTSIDE DIAMETER IS 3.5"

Explanation

THE OUTSIDE DIAMETER IS 3.5"

5. WHAT IS THE NAME FOR THIS MATERIAL?

BAR GRATING

TREAD GRATING

STEEL SHEET

EXPANDED METAL

Expanded metal is the correct answer because it is a type of material that is made by cutting and stretching a metal sheet, creating a pattern of openings. This material is commonly used for various applications such as fencing, walkways, and screens, due to its lightweight, durable, and versatile nature. It provides excellent ventilation, visibility, and drainage properties, making it suitable for a wide range of industrial and architectural purposes.

6. THE NOMINAL SIZE OF PIPE IS ALWAYS EQUIVALENT TO THE INNER DIMENSIONS OF THAT PIPE.

True

False

ALTHOUGH THE NOMINAL SIZE IN MOST CASES IS CLOSE TO THE INNER DIMENSION OF THE PIPE, IT IS NOT EXACT. EXAMPLE OF THIS WOULD BE 1/2 SCH 40 WHERE THE INNER DIMENSION OF THAT PIPE IS .622.

7. ONE DIFFERENCE BETWEEN HOT ROLL SOLID ROUNDS AND COLD ROLL IS THAT HOT ROLL WILL HAVE MORE OF A SMOOTH SURFACE.

True

False

HOT ROLL WILL HAVE MORE OF A SCALY SURFACE.

Explanation

HOT ROLL WILL HAVE MORE OF A SCALY SURFACE.

8. WHAT DOES THE 3/16" IN 1 X 3/16 BAR GRATING STAND REPRESENT?

THE DEPTH OF THE BAR GRATING

THE ROD THICKNESS OF THE BAR GRATING

THE THICKNESS OF THE BEARING BARS

THE SPACING IN BETWEEN THE BEARING BARS

The 3/16" in 1 x 3/16" bar grating represents the thickness of the bearing bars.

Explanation

The 3/16" in 1 x 3/16" bar grating represents the thickness of the bearing bars.

9. ROUND TUBING WITHOUT A SEAM IS REFERRED TO AS WHAT?

EWR

TUBING WITHOUT A SEAM

D.O.M.

PIPE

D.O.M. stands for Drawn Over Mandrel, which refers to a manufacturing process used to create round tubing without a seam. This process involves drawing a solid metal tube through a die and over a mandrel, resulting in a smooth and uniform tube with consistent dimensions. Therefore, D.O.M. is the correct term for round tubing without a seam.
