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