Question

A tensile test for a copper specimen has been performed and the following data are obtained. 

- Percentage of Elongation = 65 %

- Percentage of Reduction in Area = 39 %

- Final length after fracture = 36.1 mm

- Final Diameter after fracture = 4.25 mm & 

- Ultimate stress = 401 MPa 

 

SOLUTION:

  1.  Initial Length (in mm) = 
  2.  Final Area (in mm2) =
  3.  Initial Area (in mm2) =
