A W14x132 section has been rolled from a new experimental steel, and data has been obtained from a stub column compression test, where the initial length of the column was 12 inches. (See accompanying file StubColTestData.cvs for data.) Do not use 
the AISC Specification for this problem. 
a. Plot this load vs. deformation data, and then calculate and plot average axial engineering stress vs. axial strain. 
b. Use the results from a. to develop a column strength curve(for weak-axis buckling) in terms of critical buckling stress (Fcr) vs. normalized unbraced length (Lc/ry). Use the concept of tangent modulus (Et) and neglect imperfection effects. Plot for Lc/ry ≤ 200. 
c. Use the results from b. to develop a column strength curve (for weak-axis buckling) in terms of nominal strength (Pn) vs. unbraced length (Lc). Plot for Lc ≤60 ft.
