Select whether the following statement's are true or false: Structural safety is solely the responsibility of the aircraft manufacturer and the airworthiness authorities. If a structural component is not inspectable, it can still be certified according to one of the available design philosophies. Decreasing the stress amplitude while maintaining the mean stress means that less work or energy is applied to the structure, and thus less damage is caused resulting in a longer fatigue life.

Part A Some tire stores claim that filling your car tires with pure, dry nitrogen is much better than using plain air. They make the following claims. 1. The pressure inside N₂-filled tires does not rise or fall with temperature changes. 2. Nitrogen leaks out of tires much more slowly than air because the N₂ molecules are bigger. 3. Nitrogen is not very reactive, and moisture and O₂ in air cause corrosion that shortens tire life by 25-30% Evaluate the claim as a whole. Check all that apply. Claim passes falsifiability test. Claim passes logic test. Claim passes replicability test. Claim passes sufficiency test Claim fails all four FLaReS tests. Submit Request Answer
