For a cylindrical S-590 alloy specimen (Figure) originally 10 mm

For a cylindrical S-590 alloy specimen (Figure) originally 10 mm (0.40 in.) in diameter and 500 mm

Question:

For a cylindrical S-590 alloy specimen (Figure) originally 10 mm (0.40 in.) in diameter and 500 mm (20 in.) long, what tensile load is necessary to produce a total elongation of 145 mm (5.7 in.) after 2,000 h at 730(C (1350(F)? Assume that the sum of instantaneous and primary creep elongations is 8.6 mm (0.34in.).
