ONLY (c). 

Consider the frame system shown in Figure 4. Use the Flexibility method to carry out the following: 4. Calculate the approximate axial force in the column of the frame (no calculations for the exact axial forces in the members of the frame are a) required). The axial force in the beam is assumed to be zero. b) Determine the primary (determinate released) frame appropriate for the stability analysis of the frame and identify the reference member in the frame (the member with the maximum compressive factor 9 ). Calculate the critical compressive factor 9cr in the column and the critical intensity of the uniformly distributed load qcr (express qor as a function of El and length I). If the exact axial forces in the column and beam are 0.53ql and 0.03ql, respectively, critically assess the nature of these two members (e.g. whether normal members or members with high compression forces). ししし ET 0.8e Figure 4. to
