Explain plese

A tensile test specimen having a diameter of 5/8 in. and a gage length of 2 in. was tested to fracture The stress-strain curve from the tension test is shown in Figure P3.6. The lower plot is the expanded region OAB and associated with the strain Values given on the lower scale Solve Problems 3.6 through 3.10 using this graph. Determine the axial force acting on the specimen when it is extended by (a) 0.006 in; 0.120 in Determine the extension of the specimen when the axial force on the specimen is 20 kips Determine the total strain, the elastic strain, and the plastic strain when the axial force on the specimen is 20 kips

Explanation / Answer

From the above given data

axial force = 45N

extension =3 mm

total starin=34

Elastic starin = 25

Plastic starin = 9
