One and one-half times limit load without failure is a description of which concept?

• A. Ultimate Load
• B. Factor of Safety
• C. Limit Load
• D. Rate of Turn

Answer: (B)

The main idea here is the safety factor, which compares how much load a structure can eventually carry to the maximum load it is designed to handle safely. The limit load is the highest load the structure can support without sustaining permanent damage, while the ultimate load is the maximum load it can withstand before failure occurs. Saying you can go one and a half times the limit load without failure describes the ratio of ultimate load to limit load, which defines the factor of safety. In numbers, if the limit load is L, the ultimate load would be 1.5L, giving a safety factor of 1.5 (Ultimate Load divided by Limit Load). The rate of turn has no bearing on this concept.
