Question

A cylindrical brass specimen having a diameter of 1.10 cm and initial gage length of 4.04 cm is subjected to tensile strength test. The load-deformation values are given in the below table. The final length and final diameter of the specimen were measured as 4.33 cm and 0.92 cm, respectively. Complete the below table and plot true stress-true strain diagram and determine.

Yield strength at 0.2 % off-set method.
Poisson’s ratio of the material at 135 kN load (assume that there is no volume change)
If the material were unloaded from 175 kN, what would be its final length?

1 nm=1*10^-9 m, 1 ⁰A=10^-10 m
