Chapter 1: Introduction
Q1. What does "NPS" stand for in pipe designation?
Answer: Nominal Pipe Size
Q2. How is NPS 12 designated?
Answer: By the term Pipe, nominal diameter (in.) and weight class (Std., x-
strong, xx-strong)
Q3. What is the ASTM specification for pipes?
Answer: A Specification
Q4. What are the specification increments for plates up to 3/8-in.
thickness?
Answer: Use 1/16-in. increments for specification
Q5. What are the specification increments for plates from 3/8-in. to 1-
in. thickness?
Answer: Use 1/8-in. increments
, Q6. What are the specification increments for plates over 1-in.
thickness?
Answer: Use 1/4-in. increments
Q7. What is the cross-sectional area of a W40×297 section?

Q8. What is the permissible variation for flanges out of square for
W24×62?
Answer: Up to a total of 5/16"
Q9. What is the minimum actual length for a W30×99 beam?
Answer: 24' 11 1/2"
Q10. What is the permissible variation for a 36" deep beam, 35 ft long?

4 in flanges?
Answer: Approximately 7/16"
Q13. What is camber?
Answer: A curvature fabricated into a beam or truss to compensate for
deflection caused by loads
Q14. What do Charpy V-notch impact tests measure?
Answer: The toughness of a specimen
Q15. What is a cope in steel design?
Answer: Cutouts made in structural members to remove a flange and
conform to the shape of an intersecting member
