A bar having two sections of cross sectional area of 100mm˛ and 200mm˛ respectively. The length of both the sections is 200mm. What will be the total strain in the bar if it is subjected to axial force of 100kN and E = 105 N/mm˛?

A brass bar, having cross sectional area of 150mm˛, is subjected to axial force of 50kN. What will be the total strain of bar if E= 1.05 x 104 N/mm˛?

A composite bar of two sections of each of length 100mm, 150mm. When force is applied, all the sections causes an elongation of 0.1mm. What will the resultant strain in the bar?
