In the first set-up, a tapered bar with diameter d1 & d2 fixed between supports along its length 'L' is kept. In the second set-up, a bar of the same material and length '2L' having constant diameter 'd' is held between supports. Both the bars were heated by the same ΔT°C. What will be the ratio of maximum stress in the second set-up to the maximum stress in the first set-up if the relation between diameters of the tapered bar is d2 = 2d1.
