β Design of shafts, springs, crankshafts, and any rotating part
Detailed Explanation
This chunk highlights how different components in machinery are designed using failure theories. Specifically, many mechanical applications require attention to how parts will behave under different loads and stresses. For example, shafts and crankshafts are critical in engines, converting rotational motion into the work, and they must be designed to withstand forces without failing.
Examples & Analogies
Think of a bicycle. The pedals and crankshaft must endure not just the weight of the cyclist but also the forces when pedaling hard. Failure theories help engineers ensure these parts will not break, much like how a sturdy bridge is designed to hold the weight of vehicles without collapsing.

β Used in industries like automotive, aerospace, machine tools, biomedical implants
Detailed Explanation
This chunk lists various industries where the applications of failure theories are critical. In the automotive and aerospace fields, components such as engine parts must be incredibly reliable, while in biomedical engineering, implants should not fail inside the human body. Engineers in these industries use different failure theories and calculations to ensure that the components will perform safely under expected loads.
Examples & Analogies
Consider airplane wings, which are designed to lift tons of weight while flying at high speeds. Engineers utilize failure theories to ensure that these wings can endure the stresses from air pressure without failing. Similarly, a hip implant must be designed to withstand daily activities of a patient over many years, ensuring it remains intact and functional without causing injury.
