Express the magnitudes of the forces in pounds to three significant figures. Separate your answers with commas View Available Hint(s) (Figure 1) the free-body diagram of the joint on either side of the t is known, we can apply the equations of equilibrium to at part of the member to determine the forces at the cut ection. Since only three equilibrium equations F,-0, Σ F,-0, and Σ Mo-0) can be applied the free-body diagram of any segment, we should try to elect a cut that passes through no more than three members of the truss in which the forces are unknown. v = 0, and y,M' lb, Ib, Ib For the Howe bridge truss shown, d = 11 ft, F1 2950 lb, F2 1850 1b, Fa 2550 lb, and F4250 lb (Figure 2) Part D- The Sense of the Forces Figure く) 2012 State if the members considered in part C are in tension or compression. Complete each sentence by dragging the appropriate word into the blank. The words can be used more than once. Reset Help Mamber BC is in Member HI is in Member BH is in 3 IN NA command option
