1)A force is gradually applied at the end of an elastoplastic bar such that it is in the plastic phase. When the total magnitude of strain is ε=0.003, calculate the applied force, axial stress, elastic strain, and plastic strain. Use thefollowing material properties: E=100 GPa, H=10 GPa, and σ_y=100 MPa. The cross-sectional area of the bar is A=1.0*10^-4 m².

2)Repeat Problem P4.4 using the kinematic hardening model. For back stress, use α_n=2.5MPa.
