Root Cause Failure Analysis - Understanding Mechanical

Root Cause Failure Analysis - Understanding Mechanical Failures. Machines aren't supposed to break, and mechanical components such as shafts, fasteners, and structures aren't supposed to fail. But when they do fail, they can tell us exactly why. It may sound a little far-fetched, but experts say that the causes for more than 90% of all
