Transcribed Image Text:Question 1
A simply supported composite beam 3 m long carnes a uniformly distrbuted load of intensity
q 30 kN/m. The beam is constructed of a wood member, 100 mm wide by 150 mm deep,
reinforced on its lower side by a steel plate 8 mm thick and 100 mm wide.
Find the maximum bending stresses ow and os in the wood and steel, respectvely, due
to the uniform load if the moduli of elasticity are Ew
1 1
10 GPa for the wood and Es =
210 GPa for the steel
Find the required thickness of the steel plate so that the steel plate and the wood reach
their allowable stress values, oas = 100 MPa and oaw= 8.5 MPa, sımultaneously
12
