In the AISC manual we are given width to thickness ratio. The equation above it is how that table was made. I don’t know what number to use for mu (poissons ratio) and what number to use for the K factor
But somehow I need for the top equation to equal the bottom. I believe the K factor has restrictions (minimum numbers)
After that I need to use the top equation to F critical given E=29000 Ksi and Fy= 36 ksi after
(Second image) PLEASE HELP
Solution
Material is A36 steel with poissons ratio of 0.26 and value of plate buckling coefficient, K shall be 0.01
