Why do products fail and who finds out why? This unit enters the complex world of forensic engineering and examines how scientists analyse product failure. From investigating a ladder accident to determining the reasons behind the failures in medical products, you will understand how the ‘truth’ can be established. This study unit is just one of many that can be found on LearningSpace, part of OpenLearn, a collection of open educational resources from The Open University.
