A bar ABCD with varying cross section and subjected to axial loads is shown schematically in Figure Q3. Take modulus of elasticity of bar as 202 GPa. The length of each section L1 = 111 mm; L2 = 205 mm; and L3 = 451 mm. The cross sectional dimensions are as follows: Section 1 is square with side 49 mm, Section 2 is circular with diameter 79 mm and Section 3 is circular with diameter 32 mm. The forces are...
