Creep test has been conducted on a polymer material. The test was conducted in the tensile mode and specimen had an initial length of 130mm. The table below records the deflections (millimeters) of the specimen as a function of time (hours), at three different temperatures (70C,100C,135C). Plot the creep strain () versus time (t) curves for all temperatures on one chart. Briefly comment on the relationship between creep deformation and temperature
