An elastomeric seal in interposed between a box and it's lid

An elastomeric seal in interposed between a box and it's lid to provide waterproofness. Deformation of the seal is maintained constant. The behavior of this elastomer can be represented by a Maxwell model. Calculate modulus ( E ) and viscosity () considering that: The lid closing system causes a deformation of 5% and the initial reaction pressure is 0.1MPa. After 30 days, this reaction pressure has fallen by 10%. When the pressure reaction becomes equal to 10% of its initial value, waterproofness will not be any more provided. Calculate the duration time after which the seal will fail
