3. Two steel-made thin plates are joined together to form a beam with the shape of T. The T beam is then strengthened by assembling two wood parts as demonstrated below. E for wood and steel are 15 GPa and 225 GPa, respectively. The bending moment of 50 kN is applied to the composite beam configuration. Calculate the maximum stress in the wood and the steel parts. -200 mm- 20 mm 300 mm 75 mm 75 mm 20 mm 3. Two steel-made thin plates are joined together to form a beam with the shape of T.
