Heavy wire hanger circles, 8 nm in diameter, 60 cm to the ceiling, and the rest are either symmetric balanced with light levels in 4 lines, as if each line length 50 cm rope tension in the rope each have much value.
Heavy wire hanger circle 8 Newton diameter 60 cm to the ceiling symmetrically. And a balancing act in line with the light string line in Figure 4 is 50 cm long each strand rope tension in the rope, how much each is worth.
Hanging wire circle, heavy 8 Newton 60 cm diameter, with the ceiling as symmetry. And rest balance in horizontal with rope light 4 lines as shown. If the rope, each long 50 cm. Tension rope each line is how much.
