SUMMARY
The maximum weight of the lamp that can be supported by the cords is determined to be 24.4 lb, based on the maximum tension capacity of 31 lb per cord. To achieve equilibrium, the angle θ of cord DC must be calculated, as it directly influences the tension distribution among the cords. Without knowing θ, the validity of the maximum weight calculation remains uncertain. The tensions in the cords are T(1) = 12.63 lb, T(2) = 17.86 lb, and T(3) = 30.93 lb, which are critical for further analysis.
