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 1.8 m-high fence is to be supported by steel posts 6.0 cm in diameter that are placed every 3.0 m. Between the posts will be steel wire 3.2 mm in diameter that is woven into 5.0 cm squares.

For ambient air with U = 25 m/s, calculate the drag per post and the drag on one 5.0 cm length of wire. For the complete fence, how will the total drag on the wire mesh compare with that on the posts?
