Question

The following data are obtained from a tensile test of a copper specimen.

- The load at the yield point is 143 kN.

- Length of the specimen is 29 mm. 

- The yield strength is 71 kN/mm2

- The percentage of elongation is 48 %.

Determine the following 

Diameter of the specimen, 

Final length of the specimen, 

Stress under an elastic load of 18 kN, 

Young's Modulus if the elongation is 1 mm at 18 kN  and 

Final diameter if the percentage of reduction in area is 29 %. 

Initial Cross-sectional Area 2.01 mm2.

The Diameter of the Specimen 1.59 mm. 

Final Length of the Specimen 42.92 mm. 

Stress at the elastic load 8955.22 N/mm2.

Find:

Young's Modulus of the Specimen (in N/mm2)

Final Area of the Specimen at Fracture (in mm)

Final Diameter of the Specimen after Fracture (in mm)
