Your company design and manufacture engineering polymers with outstanding mechanical properties. During a quality control test, a 25.0-cm-long polymer sample is stretched with a constant tensile load of 20.0 kPa, it stretches to a total length of 37.5 cm in 1200 s. After removing the load, the sample recovers only to 26.75 cm. Assuming that the mechanical behavior of the polymer can be treated as a Maxwell element, estimate the time it would take for an identical (untested) sample to relax to 0.750 its original stress when a constant elongation of 50% is applied.
