4. It is proposed to place a spring in series with a Voigt element. For this model the relation between stress and strain can be written in Laplace space as, $\mathcal{L}[\epsilon] = \left(\frac{1}{E_g} + \frac{1/E_v}{\tau s + 1}\right)\mathcal{L}[\sigma]$ where the subscripts \"v\" and \"g\" refer to the Voigt element and spring element, re- spectively. 1 (a) Find the equilibrium value, $\lim_{t \to \infty} \epsilon(t)$, from a creep experiment. (b) Find the equilibrium value, $\lim_{t \to \infty} \sigma(t)$, from a stress-relaxation experiment.
