At the request of Mr. F. J. Moynihan, Motor Transportation Office, samples of broken leaf springs were examined. These samples were approximately 2-34 in. long, 3 in. wide, and 38 in. thick. The springs had been in service about five years on a five-ton truck which distributed salt on the Arsenal roads during the winter months. The samples had a very heavy coat of corrosion on both surfaces and several had transverse cracks extending almost the width of the spring. Failure by stress-corrosion or corrosion-fatigue was indicated.
