Problem 1 (20 pts): If you are given the fiber and matrix properties below and are asked to estimate the composite elastic constants (Moduli E₁, E2, G₁2 and Poisson's ratio V12)

and directional strength (X₁, Xe, Yı, Ye and S). Continuous long fiber reinforcement: Er = 400 GPa; v=0.4; or=3 GPa; Epoxy matrix: Em=3 GPa; vm -0.3; Gm= 80 MPa ; Tm = 60 MPa; Fiber volume fraction: V₁ = 60% Please give your estimate and specify the micromechanics equations you use for the estimate (if you use computer programs your solution must include code and outputs).
