1. The problem statement, all variables and given/known data Finding the critical buckling load of a really short column with wide cross section (is it still considered a column?) E = 22 GPa Yield: 300 MPa Load: 28N thickness: 0.226 mm I = 670706.51 mm^4 (is this right?) Load Applied Area (as indicated by white arrows): 190400 mm² I understand from http://www.engineersedge.com/column_buckling/column_ideal.htm that I should be applying Johnson's Formula. 2. Relevant equations Euler Buckling : [URL]http://172.31.254.243/www.engineersedge.com/column_buckling/image/column1.gif[/URL] Johnson's Formula [URL]http://172.31.254.244/www.engineersedge.com/column_buckling/image/johnson.gif[/URL] 3. The attempt at a solution Using Johnson's formula, I've found out the Critical Buckling Load (Pcr) is 57119986 N I know this is a really short structure with a wide cross sectional area so naturally the Pcr will be bigger but could someone please verify my method?
