A) Calculate the modulus of elasticity of a fiber-reinforced polymer composite under isostrain condition if the composite consists of 35% fibers and 65% polymer by volume. Also, b) calculate the percentage of load carried by the fibers. The modulus of elasticity of the fibers and the polymer are 50*106 psi and 0.5*106 psi, respectively.
