3. The Balgstuw Ramspol is an inflatable rubber dam in The Netherlands used to protect the IJssel delta against flooding. When the dam is needed, water is allowed to flow into the rubber membrane until it is at the same level as the water level on the inland side of the dam. Then, extra air is pumped inside the rubber membrane to create the dam. The total width of the dam (into the page) is 240 m. Let's assume this rubber membrane can handle a net horizontal force from the water of 1 x 10°N. If the inland water level is 3m and the sea level is 5m, as shown below, would the rubber membrane be able to hold the net horizontal force due to water? Assume static conditions. Ignore any forces generated by air inside or outside the dam and neglect the weight of the rubber membrane itself.
