A glue-laminated timber beam is reinforced by carbon fiber reinforced plastic (CFRP) material bonded to its bottom surface. The cross section of the composite beam is shown in figure below. The elastic modulus of the wood is E= 12 GPa and the elastic modulus of the CFRP is 112 GPa. The simply supported beam spans L = 6 m and carries a concentrated load P = 4.4 kN at midspan, see figure below. A If b₁ = 81 mm and b₂ = 35 mm determine: L/2 B L/2 C CFRP b₁ b₂ 250 mm 3 mm
