This is the question but without figures:
Consider a linear viscoelastic material represented by the mechanical model given in Figure 4(a).Under simple shear conditions, determine:
(a) the constitutive equation associated with this mechanical model
(b) the shear stress at time for the shear strain history given in Figure 4(b).
