A tensile test was performed on a metal specimen with a circular cross-section. The diameter was measured to be 0.550 inch. Two marks were made along the length of the specimen and were measured to be 2.030 inches apart. This distance is defined as the gage length, and all length measurements are made between the two marks. The specimen was loaded to failure. Fracture occurred at a load of 30,000 pounds. The specimen was then reassembled, and the diameter and the gage length were measured to be 0.430 inches and 2.300 inches Determine the
a. Ultimate tensile stress in ksi.
b. Elongation as a percentage.
c. Reduction in cross-sectional area as a percentage.
