A new material is being developed and tested in the lab. The column was made using the new material and was loaded to a constant axial stress of 25 MPa. The deformation is monitored over time according to the following table. The deformation is measured over a length of 250 mm. First sketch strain-time curve and describe the model. Second, determine the elastic modulus and the viscose coefficient. (40 points)
