Expert Solution
Step 1
Stress-Strain curve gives the idea of the material to carry a load or the behaviour of the material when subjected to different loads.
Given Data:-
Initial Diameter = 0.502''
Fractured Diameter = 0.412''
Original Guage Length =2.00''
Final Guage Length = 2.78''
To Find:-
1) Proportionality Limit
2) Modulus of elasticity
3) Yield Stress using 0.2% offset
4) Maximum Stress
5) Rupture Stress
6) Percentage Reduction in area
7) Percentage Elongation
