🔍 Key Concepts

• Use the BL-0026 Longitudinal Bending Stresses (PSI) table to find the maximum sagging stress for this loading condition • Understand from the salmon-colored pages how bending stress (in PSI) is converted into a sagging numeral using the printed scale/graph • Distinguish between hogging and sagging by the sign convention shown in the book (which stress values count as sagging)

💭 Think About

• From the BL-0026 table, which location shows the largest sagging stress according to the sign convention explained in the book? • Once you know that governing stress value, where on the salmon pages do you match that PSI to a sagging numeral, and how do you read the numeral between tick marks? • Do all the listed stresses contribute, or does the sagging numeral depend only on the single worst-case (maximum) sagging stress for the condition?

✅ Before You Answer

• Verify from the instructions on the salmon pages whether sagging stresses are taken as positive or negative values before choosing the governing number • Confirm you are using the correct stress type (deck or bottom / extreme fiber) that the book says controls the sagging numeral • After you pick a numeral from the scale, check that it is consistent with the PSI range for that loading condition (your numeral should fall between the values shown next to it on the salmon page).
