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. 3 ft + C D 6ft B 8 ft concrete E F-4.5 ft-4 ft 6ft | A NOTE: This is a multi-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 120 lb/ft³ specific weight, determine the force supported by members BC and DF. The force supported by the member BC is Ib. (Round the final answer to four decimal places.) The force supported by the member DF is lb.

PRO BLEM 2: A TRICKY STRUT An orange strut of length l is connected to a wall via a pi vot at the bottom. An additional (blue rope) also connec ts the strut to the wall attached at an angle 01. A load of weight W is hanging from the strut; the load makes an angle 02 with the strut as shown in the diagram. In order to stabilize the system, and additional force needs to be applied. That force, which is labeled C in the diagram, makes an angle p with respect to the strut as shown. What is o?

The following forces are acting on the bracket below. The bracket has a width w of 2 inches and a height h of 3 inches. The bracket is in equilibrium (not accelerating). Determine F3y knowing F1x-98 lbf and F1y=195 lbf. For this question, what is F3.y in Ibf? Note that the y- direction is pointing up, so if the force is pushing down on the bracket, it has a negative magnitude. 39
