Rubber particles, roughly 1mm in diameter, have been added to an epoxy resin to increase its resistance to crack growth. Estimate the Young's modulus of the composite, given that the Young's moduli of the epoxy and the rubber are, respectively, 2GPa and 10MPa, and that the volume fraction of the rubber particles is 5%.
E (in GPa):

E= (Er*Ee)/(ErVe+EeVr)
