A continuous and aligned fiber-reinforced composite having across-sectional area of 1190 mm2 is subjected to an externaltensile load. If the stresses sustained by the fiber and matrixphases are 144 and 2.16 MPa, respectively, the force sustained bythe fiber phase is 74400 N, and the total longitudinal strain is0.00119, determine the following: (a) The force sustained by thematrix phase (in N). (b) The modulus of elasticity of the compositematerial in the longitudinal direction (in GPa). (c) The modulus ofelasticity for the fiber phase (in GPa). (d) The modulus ofelasticity for the matrix phase (in GPa).
