Eliot is building a metal fence using your knowledge of expansion and contract decide what time of the year will be the best time of the year to build the fence.

Based on the factors or expansion and contraction, the best time of the year for Eliot to build a metal fence would be during fall and winter.

Explanation:

If Eliot is advised to build the fence in Summer, he would possibly build the fence by leaving no sapping or lag in the fence and end up building a tightened fence. A tightened fence would contract more in the winters and eventually deform due to increased tension. A fence built in the winters will be already contracted after coming in contact with the atmosphere. The expansion that would occur in summers would only loosen up the fence but won't break it. Hence, it would be preferable to build the fence during fall or winter.
