During a creep test (constant stress equal to 3.5 MPa) a material has an initial strain of
10 and a strain of 2 x 10* after 30 days. The same material was also submitted to a
relaxation test (constant strain equal to 1.5 x 104). During the relaxation test, determine the
stress after 30 days. Assume that the material follows the Maxwell model.
