1. The problem statement, all variables and given/known data the question is in the picture. the rectangular steel bar shown supports a concentric load of 13000lbf. Both ends are fixed. If te modulus of elasticity is 29x10^6 lbf/in^2, what is the maximum length the rod can be without experiencing buckling failure? 2. Relevant equations 3. The attempt at a solution what I got was 81.3365. but I am not sure. moment of inertia I got .1953125 from the cross section and just used Pcr = (I*E*(pie)^2)/(K*L^2) used .65 for K coz its fixed fixed.
