Answered by ajfour last updated on 12/Jan/19

$$2T\cos \alpha +mg\cos \gamma =mg$$$$2T\sin \alpha \cos \varphi =mg\sin \gamma$$$$\frac{l}{2}\cos \alpha =L\cos \gamma$$$$\frac{l}{2}\sin \alpha \cos \varphi +L\sin \gamma =\frac{a\sqrt{3}}{2}$$$$andeven$$$$\frac{l}{2}\sin \alpha \sin \varphi =\frac{a}{2}$$
