Compute the longitudinal tensile strength of an aligned glass fi

Compute the longitudinal tensile strength of an aligned glass fiber-epoxy matrix composite in which the average fiber diameter and length are 0.010 mm (4 ( 10-4 in.) and 2.5 mm (0.10 in.), respectively, and the volume fraction of fibers is 0.40. Assume that (1) the fiber-matrix bond strength is 75MPa (10,900psi), (2) the fracture strength of the fibers is 3500MPa (508,000psi), and (3) the matrix stress at fiber failure is 8.0MPa (1160psi).
