A $12\mathrm{.}5-mm-(0\mathrm{.}50-$in$.-)$ diameter cylindrical rod fabricated from a $2014-$T$6$ alloy is subjected to a repeated tensioncompression load cycling along its axis. Compute the maximum and minimum loads that will be applied to yield a fatigue life of $1\mathrm{.}0107$ cycles. Assume that the stress plotted on the vertical axis is stress amplitude, and data were taken for a mean stress of $50$MPa $(7250).$ Also calculate the min and max Force

$1045$ steel bar is subjected to repeated ression stress cycling along its axis. If the load $($bf$),$ compute the minimum diameter to ensure that fatigue failure will not a factor of safety of $2\mathrm{.}0.$

For a cylindrical S$-590$ alloy specimen originally in$.)$ in diameter and $500mm(20$ in$.)$ long, what tensile load is necessary to produce a total elongation of $145mm(5\mathrm{.}7$ in$.)$ after $2,000h$ at $730$ degree $C(1350$ degree F$)?$ Assume that the sum of instantaneous and primary creep elongations is $8\mathrm{.}6mm(0\mathrm{.}34$ in$.).$
