A tensile test wаs perfоrmed оn а specimen with а circular crоss section. The diameter was measured to be 0.770 inch. Two marks were made along the length of the specimen and were measured to be 2.350 inches apart. This distance is defined as the gage length, and all length measurements were made between the two marks. The specimen was loaded to failure. Fracture occurred at a load of 20,500 pounds. The specimen was then reassembled, and the diameter and gage length were measured to be 0.278 inch and 2.625 inches. Determine the reduction in cross-sectional area as a percentage.
