Mechanical failure refers to the breakdown of a machine or component due to various factors, such as wear and tear, design flaws, or improper maintenance. This failure can lead to the malfunction of equipment, resulting in decreased performance or complete inoperability. Common examples include a car engine failing to start or a computer hard drive crashing. When mechanical failure occurs, it can have significant consequences, including safety hazards and financial losses. Regular inspections and maintenance are essential to prevent such failures. Understanding the causes of mechanical failure helps in developing better designs and improving the reliability of machines and equipment.
