Question 2 1.5 pts A 150UC37.2 structural steel (E = 200,000 MPa) column is to be used as a 3 meter long column. The column is having fixed-support at both the ends (k = 0.7). A vertical load of 2000 KN is applied on the column. The column is constrained from failure in the weak direction. What is the Critical Stress (@cr). (in MPa) of the Column?
