An overhead line has a span of 200 m, the weight of the line conductor is 0.5 kg/m. If the maximum tension in the line is 1000 kg, then the sag in the line is
- A. 1.5 m
- B. 2.0 m
- C. 2.5 m
- D. 5.0 m
Answer: C. 2.5 m
Explanation: Sag S = w L² / (8 T) = (0.5 × 200²) / (8 × 1000) = 20000 / 8000 = 2.5 m.
