2 cards from this section. Quick, good the night before a test.
Define the slenderness parameter (cid:21).
Refer to the definition discussed in class.
What is the critical buckling stress (F_{cr})?
Think about the stress levels in relation to yield strength.
What does the slenderness parameter (cid:21) help assess?
Focus on what the parameter measures in steel columns.
True or False: The Euler equation is used when (cid:21) is less than p2.
Think about the relational conditions provided in our discussions.
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.
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?
Focus on table entries for (cid:21) results.
