Three identical 8.60-kg masses are hung by three identical springs, as shown in the figure. (Figure 1) Each spring has a force constant of 5.90 kN/m and was 11.0 cm long before any masses were attached to it. Make a free-body diagram for the top mass. Draw the vectors starting at the black dot at the center of the top mass.

Part A Cables of negligible weight support the loading shown. (Figure 1) If W1 = 5.00 lb , W2 = 71.0 lb , yB = 4.50 ft , yc = 7.50 ft , YD = 2.50 ft , and rc = 2.00 ft , find æg- Express your answer numerically to three significant figures in feet. • View Available Hint(s) ΠV ΑΣφ It vec IB = ft Submit

Please help and include units

I need help with this question, it really has me stumped. The values I have depicted are said to be incorrect, I have also tried the same values but positive for each part and it was incorrect as well. Any help would be appreciated, thanks.
