Question 3 A rectangular Timber column, 200 mm by 90 mm, is reinforced by the addition of two Aluminium rods, each of diameter 20 mm within the Timber cross-section. The compound column carries an axial load of 400 kN. E for timber =, 15 kN/mm2; E for aluminium = 90 kN/mm². %D (i) Determine the stress in the Timber column; (ii) Determine the stress in the Aluminium rods; (ii) Determine the change in length of the column if the original length is 1.5 m.
