A rectangular strain rosette, shown in figure, gives following readings in a strain measurement task, $\epsilon 1 = 1000\times 10^{-6}$ , $\epsilon 2 = 800\times 10^{-6}$ and $\epsilon 3 = 600\times 10^{-6}$ . The direction of the major principal strain with respect to gauge
(a)$0^{0}$ (b)$15^{0}$ (c)$30^{0}$ (d)$45^{0}$
