If some of the compliances and strengths of an orthotropic lamina satisfy certain conditions, the maximum strain criterion failure surface will intercept the horizontal axis at a point like \(\left(\sigma_{1}, 0\right)\) instead of at \(\left(s_{\mathrm{L}}^{(-)}, 0\right)\), as shown in Figure 4.12. Express these conditions in terms of an inequality.
