Incorrect. If F2.A exceeds F2.allow, then the force in member (2) will control the capacity of the two-bar assembly,
and the Load Case B assumption should be used. Otherwise, F1.B Exceeds F1.allow, the force in member (1) will
control the capacity of the two-bar assembly, and the Load Case A assumption should be used.
Enter the forces in the members corresponding to the correct maximum load case assumption, Load Case A or Load Case B.
