A continuous and aligned fiber–reinforced composite having a cross-sectional area of 1130 mm² (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 lb_f); and the total longitudinal

strain is 1.25 ×10⁻³, determine the following:

(a) The force sustained by the matrix phase

(b) The modulus of elasticity of the composite material in the longitudinal direction

(c) The moduli of elasticity for fiber and matrix phases
