Fatigue is failure due to a stress being repeatedly applied. to a metal. After a number of cycles the component fails.. Examples include aircraft, axles, and shafts.. Stresses. Cyclic – tension compression fully reversed. Signs and symptoms. pain. swelling. bruising. discolored skin around the affected area. angulations – the affected area may be bent at an unusual angle. the patient is unable to put weight on the injured area. save you money. .. 60 – 70% of the . hours. . spent thawing a culvert . are . used to FIND .
