A horizontal rigid bar c-c is subjecting specimen a to tension and specimen b to frictionless compression such that the bar remains horizontal. The force F is located at a distance ratio of 2:1. Both specimens are incompressible and have an original cross-sectional area of 1 in2 and the original lengths are a = 8 in. and b = 4.5 in. The material for specimen a has a true stress-true strain curve of σ = 100,000ε05. Plot the true stress-true strain curve that the material for specimen b should have for the bar to remain horizontal during the experiment.
