Assume that you have a linear viscoelastic material whose response can be predicted

by the three$-$parameter solid $($Zener$)$ model. Construct plots of E$($t$)$ versus log time

given that the solid exhibits two characteristic relaxations, where the strength of the

first relaxation is one$-$fourth that of the second. Also, determine the ratio of the two

relaxation times where it becomes difficult to separate the two relaxation processes.
