A 5-mm-thick rectangular alloy bar is subjected to a tensile load P by pins at A and B, as shown in the figure. The width of the bar is w= 26 mm. Strain gages bonded to the specimen measure the following strains in the longitudinal (x) and transverse (y) directions: Ex = 840 με and Ey = -265 με. (a) Determine Poisson's ratio for this specimen. (b) If the measured strains were produced by an axial load of P = 18 kN, what is the modulus of elasticity for this specimen?
