6. The stress-strain diagram for an aluminum alloy specimen having an original diameter of 0.5 in. and a gage length of 2 in. is given in the figure. Determine, approximately, the modulus of elasticity for the material, the load on the specimen that causes yielding, and the ultimate load the specimen will support.
