The soles in athletic shoes are made of viscoelastic foam. The soles tend to flatten and get thinner overtime. Consider a sole sample of surface area A = 20 cm- and thickness t = 8 mm. Modulus of elasticity E - 1.3 Pa and viscosity / = 5.28+5 Pa.s. A long-term experiment is conducted by applying a constant weight of 100 kg on the sole sample. The deformation (ie, loss in thickness) is measured over a 1-year period. Calculate the deformation of the sample after 1 year: mm (3 significand digits)
