A steel column with a yield strength of 40 ksi has a Kl of 24 ft and an r_min of 4 inches. Calculate the slenderness parameter and determine what equations apply.
💡 Hint: Substitute these values carefully along with numerical output.
You find that (cid:21) = 0.83 leads to a yield strength of 36 ksi in Table 19.1. What is the design stress, and how would this affect your engineering decision?
💡 Hint: Focus on table entries for (cid:21) results.
