Show transcribed image text A breakwater along an oceanfront is to be constructed of concrete. and the formwork for retaining the concrete while it is poured is shown. For every 8 ft of width (into the plane of the figure), the formwork has a horizontal support BC and a support DF. The stakes at points A, E, and F may be modeled as pins, and the weights of all members except the concrete may be neglected. If the concrete is modeled as a fluid with 90 lb/ft3 specific weight, determine the force supported by members BC and DF.
