A timber beam with a rectangular cross-section 150 mm×150 mm is reinforced by a steel plate of thickness 6 mm and the same width of 150 mm as the beam being bolted to one face (Figure 22.15). When the composite is subject to an axial load, what will be the stress in the steel when the stress in the timber is 6 MPa and the value of the axial load? The steel has a modulus of elasticity of 200 GPa and the timber a modulus of elasticity of 8 GPa.
