a bar of cross section is pulled aciallaxially. Each side of the bar is 10mm amand the gauge length of the bar is 200mm. The young modulus of rodrods material is 80Gpa. The mamum elastic strain is 0.5 %. Calculate the load required to achieve gauge length 210mm for the following conditions condition 1: the bar is made of an ideal elasto plasticaterial condition 2: the strain hardening exponent of the material is 0.2 and strength coefficient is 1000mpa
