look for two things: horizontal component and vertical component of T1 and T2 the horizontal component should cancel each other while the vertical component should balance T3

T1x sino1+ T2sino2= T3 ???
experimentX
  • experimentX
yes ... now express T1 interms of T2 and T3

\[ T_1 \sin \theta_1 + T_2 \sin \theta_2 = T_3 ---(1)\\ T_1 \cos \theta_1 = T_2 \cos \theta_2 ---(2)\\ T_2 \cos\theta_2 \sin \theta_1/\cos \theta_1 + T_2 \sin \theta_2 = F\\ T_2 (\sin\theta_1 + \sin\theta_2) = F \cos \theta_1 \\ T_2 = F \cos \theta_1/(\sin\theta_1 + \sin\theta_2) \\ T_1 = F \cos \theta_1/(\sin\theta_1 + \sin\theta_2)* \cos\theta_2/\cos\theta_1\\ \]
