Ch. Ex. 112 A breakwater along an oceanfront is to be constructed of concrete Correct Response Do not round intermediate calculations; however, for display purposes, report intermediate steps rounded to four significant figures. Give your final answer (s to four significant figures 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 3 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 200 lb/ft specific weight, determine the force supported by members BC and DF 2 ft. 6 ft 7 ft E concrete 4.4ft- 4 ft. 8 ft lb 9888 BC lb DF 12630
