Mopar_Mudder: Your answer in post 1 looks correct, for a frictionless system. The tensile force applied to each side of the scale would be approximately 229.3 N. The force on the scale actually would be slightly imbalanced (228.9 N to the left, and 229.6 N to the right), but the friction in the system is probably sufficient to prevent the scale from moving to the right. In fact, the scale reading might be significantly less than 228.9 N, due to losses to friction in the pulley axles.
