The body of a formula one racing car is made up of C-fiber/ Polyester. The weight fraction of C-fiber is 55% in final composite. If the modulus for C-fiber and polyester resin is respectively 400 GN/m ² and 3.45 GPa, find out the modulus of C-fiber/ Polyester laminate. Also calculate the fraction of externally applied load taken by the C-fiber. Find out the longitudinal tensile strength (σ _LTU ) for the laminate. The tensile stress at fiber breaking elongation is 2.1GPa for C-fiber and 0.045 GPa for polyester.      [ ρ _C-fiber = 1800 Kg/m ³  and ρ _polyester = 1100 Kg/m ³ ]
