A flexible chain of mass $\displaystyle m$ hangs between two fixed points at the same level. The inclination of the chain with the horizontal at the two points of support is $\displaystyle 30^{\circ}$. Considering the equilibrium of each half of the chain, the tension of the chain at the lowest point is $\displaystyle \_\_\_\_$.
