#98. A steel coupon tested to ASTM tension standards shows yield at 52 ksi and ultimate at 67 ksi. Which interpretation is most accurate for structural design checks?

Only elongation controls member nominal strength

Yield and ultimate are always identical for structural steels

Yield strength primarily governs service-level inelastic onset, while ultimate indicates maximum tensile capacity

Ultimate strength replaces all need for yield checks in ASD/LRFD
