- 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. 39An exhaust system for a pickup truck is shown in the figure. The weights Wh, Wm, and W; of the head-pipe, muffler, and tailpipe are 9, 86, and 41 N, respectively, and act at the indicated points. If the exhaust-pipe hanger at point A is adjusted so that its tensions Fa is 62 N, determine the required forces in the hangers at points B, C, and D so that the force-couple system at point O is zero.
