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 suffer from fatigue over time, leading to potential failures if not properly maintained.

Automobile Parts: Various components of a car, such as the engine, suspension, and chassis, are under constant stress while the vehicle is in operation. Over time, this can lead to fatigue and eventual failure of these parts.

Bridges: The structural components of bridges, particularly suspension bridges, are under constant stress due to the weight they support and environmental factors like wind and temperature changes. This can lead to fatigue in the metal components, potentially causing structural failures over time.
