Chapter 10, Problem 10.21SP
A 12.5-mm-diameter steel rod was subjected to a tension test. After rupture, it was determined that the original 50-mm gage length had elongated to 60.7 mm. The minimum diameter at the fracture point was measured to be 10.7 mm. Compute the percent elongation and percent reduction in area.

A 200mm long rod with a diameter of 50mm is loaded with a 4kN weight. The rod final length 201.314mm and final diameter 42mm the load at fracture is 2.5kN and the maximum load is 3.5KN.
1. Calculate percentage of reduction in area
2. Calculate elongation
Determine the initial length of a tensile specimen that has a percentage of elongation as 43 % and the final length at fracture 67 mm.
39)A tensile test specimen has a gage length=3.0 inches and a diameter= .75 inches. Yielding occurs at a load of 38000lbs. The corresponding gage length=3.0103 inches (neglect the .0.2% yield point). The maximum load of 54000lbs is reached at a gage length =3.453 inches. If fracture occurs at a gage length of 3.873inches, determine the percent elongation at fracture (Round to the nearest whole %)
