Q2: Consider a bar shown in figure Q2 with an axial load P = 75 kN applied as shown. The bar is split into 2 finite elements. Element 1 is made of a steel alloy with E = 225 x 10³ Nmm2 with a cross sectional area, A = 400mm?. Element 2 is made of a polymer with E = 25 x 103 Nmm? with a cross sectional area, A = 800 mm?. Nodes 1 and 3 are fixed.
