Problem 6: A composite is composed of graphite fibers in an epoxy matrix and has a cross-sectional area of 0.25 in? The graphite fibers constitute 63 percent of the cross sectional area. If the composite supports a total load of 34,000 pounds, calculate the portion of the load supported by the graphite fibers. Assume the best case scenario, where the strain of the matrix is equivalent to the strain of the fibers. The modulus values for the fibers and the matrix are: E = 0.6 x 10 psi E = 58 x 10' psi matrix fibers
