Forensic engineers use their knowledge of engineering principles, along with their experience in working with them, in examining evidence related to legal matters that must be settled. In this capacity, they investigate cases such as car accidents, mechanical failures and explosions to determine the exact cause.Analyzing various structural problemsWhen forensic engineers analyze structures, including bridges or buildings, they are determining why that particular structure collapsed. In the process, they conclude whether poor construction, lack of maintenance or bad weather caused the structural defect.Analyzing mechanical failuresAs part of their training, forensic engineers learn about the possible mechanical failures of several systems, including water pipes, air conditioning and heating
