A composite beam of steel and wood is loaded as shown. The dimensions of the wood block are 4.00 in by 16.0 inches, with steel plates that are 4.00 in wide and 0.75 in thick. The load varies along the beam as, w(x) 100 5x2 where x-0 at the wall, x is in feet, and the load is in kip/ft. The length of the beam is 15 feet. Assume all within elastic limit. Determine The reactions at the wall a....
Figure 2a shows a composite beam made by placing three steel plates inside a wooden section. (a) Determine the maximum bending stress developed in the wooden section and steel plate if the beam is subjected to allowable bending moment, M of 20 kN.m. Given that the Modulus of Elasticity of wood is 13.1 GPa and steel is 200 GPa. [14 Marks] Figure 2a: Composite beam (b) Figure 2b shows another beam without steel plates. Suggest the maximum bending stress for...
Page 7 of 9 Q4. (30%) Composite Beam Three identical wooden beams and two identical steel plates are bolted together to form the composite shown in the sketch. Determine the largest allowable bending moment, Malom, when the member is bent about the horizontal axis. Include sketch of transformed area, and list all assumptions and equations.
