Fatigue is estimated to cause 90% of all failures of metallic structures. Give three typicalexamples of components that suffer from fatigue

Aircraft Components: Many parts of an aircraft are subject to constant stress and strain during flights, such as the wings, engine components, and the fuselage. These parts can experience fatigue over time due to the repeated takeoffs, landings, and changes in pressure and temperature.

Automobile Parts: Various components of a car, such as the engine, suspension, and chassis, are subjected to repeated stress during operation. Over time, this can lead to fatigue and eventual failure of these components.

Bridges: The components of a bridge, particularly the supporting beams and cables, are under constant stress due to the weight they support and environmental factors like wind and temperature changes. This can lead to fatigue over time, which can eventually cause the structure to fail.
