The double pendulum shown consists of two particles with masses m1 = 7.5 kg and m2= 12 kg connected by two inextensible cords of length L1= 1.4 m and L2= 2 m and negligible mass. If the system is released from rest when θ = 10° and ϕ = 20°, determine the tension in the two cords at the instant of release.
