2. The engineer stress-engineer strain curve of uniaxial tensile test of 7075-T651 Aluminum is shown below. Point A is taken as the proportional limit with the values of engineering strain and stress shown next to it. 1) Please calculate the Young's modulus; (10 pts) 2) If the specimen is loaded to point B (engineering strain of 0.0252 and stress of 565 MPa) and then completely unloaded, what is the value of the plastic strain?
