4) 20 Marks A builder strengthens a 150 mmx 250 mm timber beam by connecting three 10 mm thick steel plates to the top and the two sides of the beam as shown below (there is no steel plate on the bottom). The beam acts compositely. It should be assumed that Eimber 10000 MPa and Esteel 200000 MPa and the materials exhibit linear elastic behaviour. The beam has a total length of 5 m. Steel has a density of 7800...
