Acontinuous and aligned fibrous reinforced composite having a cross-sectional area of 970 mm2 is subjected to an external tensile load. if the stresses sustained by the fiber and matrix phases are 215 mpa and 5.38 mpa, respectively, the force sustained by the fiber phase is 76,800 n, and the total longitudinal composite strain is 1.56 × 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
