Which specification describes the standard 3/8 inch galvanized aircraft cable with 7x19 construction and 14,400 lbs tensile strength?

• A. 3/8 inch Galvanized Aircraft Cable, 7x19 construction, 14,400 lbs tensile strength
• B. 1/2 inch stainless steel cable, 7x19, 20,000 lbs
• C. 1/4 inch galvanized aircraft cable, 7x19, 7,500 lbs
• D. 3/8 inch galvanized aircraft cable, 1x19 construction, 10,000 lbs

Answer: (A)

Understanding cable specs: you want a description that matches the exact diameter, construction, and strength. The standard combination for a 3/8 inch galvanized aircraft cable uses a 7x19 construction, which means seven strands of nineteen wires each. This pattern gives a good balance of strength and flexibility, so it can bend around pulleys and fittings without kinking, unlike tighter, less flexible constructions. The specified tensile strength of 14,400 lbs is the typical breaking strength for that size and construction, which also aligns with common working-load expectations when you apply a safe-use factor. Galvanizing adds corrosion resistance for outdoor or mooring use, which is why the galvanized version is preferred in many field applications. Other choices deviate in material, diameter, construction, or strength, so they don’t describe the same standard combination. For example, stainless steel isn’t galvanized, a different diameter changes the strength, a different construction (like 1x19) changes flexibility, and a much lower breaking strength wouldn’t match the 3/8 inch, 7x19, 14,400 lbs spec.
