"Beryllia $($BeO$)$ is assumed to have an activation energy of $525$ kJ$/$mol$.$ Berylia$($BeO$)$ has load of $12\mathrm{.}4$MPa, and at temperature $1300$C$,$ the creep rate $()$ is $300$x$10^-6/$hours

$($a$.)$Determine the creep rate $()$ at $1000$C and $12\mathrm{.}4$ MPa of applied stress

$($b$,5$ pt$)$ Calculate the time of BeO cylinder at at $1000$C and $12\mathrm{.}4$ MPa if $2\%$ total strain is permissible"
