Answer 2

Question: If overhead electric cables are being laid in summers, should they be tightened up or left a little loose? Justify your answer.

Solution: Overhead Power Lines must be left a little loose to allow for contraction during winter.

Explanation: Overhead electricity wires installed on poles expand during hot weather and contract in cold weather. The wires between two poles are given a certain amount of sag so that they may contract in winter without snapping.
