Example:

You need to design a nanocomposite material made from PA$6/$graphene to be used in aerospace applications. The glass transition temperature of this epoxy is $\backslash (72^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$ While in use, the nanocomposite will be subjected to a permanent tensile stress for a period $(\backslash (\backslash$mathrm$\{$t$\}\_\{\backslash$text $\{$use $\}\}\backslash ))($creep experiment$)$ at $\backslash (55^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash ).$ You need to do the necessary creep experiment in the lab to predict the performance of this Nanocomposite by applying the same stress value but at different temperature and different time. The temperature in the lab will be $\backslash (62^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ during $\backslash (\backslash$mathrm$\{$t$\}\_\{\backslash$mathrm$\{$lab$\}\}=4\backslash )$ hours. For how long can this nanocomposite be used at $\backslash (55^\{\backslash$circ$\}\backslash$mathrm$\{$C$\}\backslash )$ under the same tensile stress? $($Hint$-$ use the WLF equation$).$
