The factors shall be selected to produce which factored force effect?

• A. total extreme
• B. minimum value
• C. typical
• D. average

Answer: (A)

The main idea is that design uses factored loads to produce the most severe, or total extreme, force effect. By applying load factors to the actions (dead load, live load, wind, etc.), engineers look for the combination that yields the largest moment, shear, or axial force the member could experience. Designing to this extreme effect ensures the structure can safely resist the worst credible condition, not just typical or average conditions. That’s why the best answer is the total extreme. The other options describe less severe cases that wouldn’t guarantee safety under extreme loading.
