A third-point bending test was performed on a 100 * 150 mm wood lumber according to ASTM D198 procedure with a span of 1.8 m and the 150 mm side is positioned vertically. A strain gauge is glued at the center point between the supports. The strain gauge is zeroed at the start of the test when the force is zero. A strain of 0.00456 is measured when the combined load is 6.672 kN and the load–strain curve is in the linear range. Determine the flexural modulus of elasticity. If the maximum combined load on both loading bearings was 22.722 kN, calculate the modulus of rupture.

A composite primary steel beam with a span of 8m supports a secondary beam at midspan, which applies an characteristic (unfactored) load of 239kN to the primary beam. What elastic modulus (in cm³) does the beam require to be able to carry the load if the allowable stress due to the characteristic loads is 210N/mm2? It may be assumed that the elastic modulus required for the composite beam is 63% of that required for the equivalent non-composite beam.
