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 6 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.
NOTE: This is a muiti-part question. Once an answer is submitted, you will be unable to return to this part.
If the concrete is modeled as a fluid with
180lb/ft3 specific weight, determine the force supported by members BC and DF
The force supported by the member
BC is ...........lb. (Round the final answer to four decimal places.) The force supported by the member DF is ..........lb.
