, a versatile research associate, is struggling with rheology experiments because of her lack of knowledge in this field. She has synthesized a complex polymeric system. Please help! (a) (8) TP wants G' and G'' versus frequency plot of the sample she synthesized. She went to the rheometer and ran this experiment three times. She kept the strain amplitude constant for each experiment, as she should. However, she used different strain amplitude (percent) for each of her experiments, =1%,=10% and =35%. She finds beautiful overlap of the data for of 1% and 10% but the data taken at =35% does not match. Her experimental protocol is meticulous, everything including temperature, loading, sample geometry, gap, etc., has been flawless. What do you think is happening here? Please explain as completely as possible. Tell TP how to do such experiments. (b) (8) TP also needs steady shear viscosity vs shear rate data for this sample. When she starts to run the experiments, she has to stop the experiment midway as she is trying to get higher shear rate data, because the rheometer torque transducer overloads. Please suggest to TP what alternative experiment she could run to get the steady shear viscosity profile as a function of shear rate
