A rod, $180$ mm long and $590$ mm$2$

in cross$-$section, made of this alloy and

operating at $120$C$,$ is not to creep more than $5$ mm in $3000$ hours. Calculate the

maximum admissible axial load which can be applied for the safety factor $2\mathrm{.}5.$ Material Constant $=7\mathrm{.}751$x$10-15.$ n$=4\mathrm{.}4208$
