Reference no: EM133201718

A crosslinked rubber (ρ = 0.91 g.cm-3) sustained a stress of 120 kPa when stretched 60% of its original length at 45 °C. Following aging in an oven at 135 °C for 5 days, 15% of crosslinks were lost. Calculate the stress that the aged rubber band will sustain if stretched 50% its original length at 45 °C.
