Acontinuous and aligned fiber reinforced composite having a cross-sectional area of 1130 mm^2 (1.75 in.^2) is subjected to an external tensile load. if the stresses sustained by the fiber and matrix phases are 156 mpa (22,600 psi) and 2.75 mpa (400 psi), respectively; the force sustained by the fiber phase is 74,000 n (16,600 lbf); and the total longitudinal strain is 1.25 10^ -3, determine: (a)the force sustained by the matrix phase, (b)the modulus of elasticity of the compos- ite material in the longitudinal direction, and (c) the moduli of elasticity for fiber and matrix phases.
