Problem 13.3 Consider two bars, 1 and 2, made of two different materials. Assume that these bars were tested in a uniaxial tension test. Let F, and F2 be the magnitudes of tensile forces applied on bars 1 and 2, respectively. E, and E2 are the elastic moduli and Aj and A2 are the cross-sectional areas perpendicu- lar to the applied forces for bar 1 and 2, respectively. For the conditions indicated below, determine the correct symbol relat- ing tensile stresses o and o2 and tensile strains e and €2. Note that ">" indicates greater than, "<" indicates less than, "=" indicates equal to, and "?" indicates that the information provided is not sufficient to make a judgement. (a) If A1 > A2 and F1 = F2 then o1 >= ? < o2 and e1 >=? < €2. (b) If E1 > E2, A1 = A2 and F1 = F2 then o1 >= ? < 02 and 1 >= ? < 62 %3D
