This report covers tests that were made to determine stresses in the journal area of car axles. The test machine used did not simulate track impacts normally encountered and the stresses, therefore, represent only the static load on a rotation journal. The static load was increased 50 percent above the normal maximum load that a 5 1/2-inch journal carries. Low stresses were obtained under these extreme laboratory test conditions, there is no indication that the dynamic blows encountered in normal road service would increase the stress in the journals in sufficient degree to cause stresses that would lead to axle failures in the journal area.
