a light fixtures of 80.o N hangs from a verttical chain that is tied to two other cables that are fastened to support. Both the upper cables make an angle of 37.0 with respect to the horizontial. calculate the tension in the left and right cables
The sum of the horizontal tension components is zeo and the sum of the vertical tension components equals the weight. The two tension forces are also equal in magnitude, due to symmetry.
