please answer clearly with steps and the correct answer.

3.1. Chain-link fence To predict the ability of a chain-link fence to withstand high winds, an estimate is needed for the horizontal force that might be exerted on it. The 1.8m-high fence is to be supported by steel posts 6.0cm in diameter that are placed every 3.0m. Between the posts will be steel wire 3.2mm in diameter that is woven into 5.0cm squares. For ambient air with U=25m/s, calculate the drag per post and the drag on one 5.0cm length of wire. For the coniplete fence, how will the total drag on the wire mesh compare with that on the posts
