Mechanical failure refers to the breakdown or malfunction of a mechanical component, system, or device, which occurs when it cannot perform its intended function due to defects, wear, or other issues. This can result from factors such as material fatigue, improper maintenance, design flaws, or exceeding operational limits. Mechanical failures can lead to safety hazards, equipment damage, and decreased efficiency, impacting various industries, including manufacturing, automotive, and aerospace. Understanding the causes and implications of mechanical failure is crucial for effective maintenance strategies, design improvements, and safety protocols to prevent accidents and ensure reliable operation.
