Introduction: Engineering disasters and understanding failures — Lesson 2

This lesson covers the importance of failure analysis and prevention in the heavy engineering industry, particularly in the manufacturing and usage of mechanical components. It discusses the consequences of component failure, including service disruption, potential loss of life, property damage, and reduced reliability. The lesson also explains the process of failure analysis, which involves a systematic approach to identify potential causes of failure and determine the most probable causes. It highlights the importance of understanding the root causes of failure to prevent future occurrences. The lesson further discusses the different stages of product failure and the need for proper training, motivation, and installation to prevent failures.
