A 6 metre long supported wooden beam of rectangular section 10 cm $$ \times $$ 20 cm deep is strengthened by mild steel plates 0.5 cm $$ \times $$ 10 cm wide at the top and bottom fibre over the entire length. Find the minimum supportable uniformly distributed load considering failures in steel and wood due to flexure. Weakening of wood due to screws and weakening of the steel plates due to drilled holes may be ignored. GATE ME 1987 Strength of Materials - Pure Bending Question 9 English
Permissible tensile stress for steel = 156.8 N/mm2
Permissible tensile stress for steel = 14.89 N/mm2
Young's modulus of mild steel = 1.96 $$ \times $$ 105 N/mm2
Young's modulus of wood = 0.117 $$ \times $$ 105 N/mm2
