Can you please explain and answer my question about Materials Science
1. The stress-strain diagram below for carbon steel was obtained by tensile testing. a) Elastic modulus? b) The highest load that the cylindrical sample with an initial diameter of \( 9.4 \mathrm{~mm} \) can carry? c) How long will a \( 254 \mathrm{~mm} \) long bar extend under \( 455 \mathrm{MPa} \) stress?
Expert Answer
a)we know that elastic modulus E is given by E=stressstrain so we will find this in linear region point 1 = E = 103.4/0.0005 = 206GPa point 2 = E = 20
