Consider three rods of length L_(1), L_(2) and L_(3) espectively joined in series. Each has same cross - sectional area with Young's moduli Y, 2Y and 3Y respectively and thermal coefficients of linear expansion alpha, 2alpha and 3 alpha respectively. They are placed between two rigid fixed walls. The temperature of the whole system is increased and it is found that length of the middle rod does not change with temperature rise. Find the value of (9L_(1))/(L_(3)) .
