A uniform light rod is kept in horizontal equilibrium under the influence of fore forces as shown above, which of the following equations correctly represents the condition of equilibrium for the rod
F1 + F2 = F3 + F4
F1 + F2 - F3 + F = 0
(F1 + F2)ab = (F3 + F4)cd
F1a + F2b - F3c - F4d = 0
Correct answer is D
