2. A truss is shown in the figure below. a) Based on the number of joints and members, discuss about the stability of the truss b) Determine the reaction forces at supports.. c) Use "the method of sections" to determine the forces in members ED, EH, and GH, d) Determine whether each member is in tension (T) or compression (C). 50 kN 40 kN 2 m -2 m- -2 m D E F O 1.5 m C -30 kN G H 1.5 m B 40 kN I A 1.5 m 1. Given the specified tensions in cables AB and AC, calculate the resultant moments produced by these tensile forces at point A about point 0. ス 6 m 1.5 m B 2 m FB = 55 N 4 m 4 m Fc = 40 N A 3 m

The truss shown has members having a cross sectional area of 1400 mm2. Find the stresses in members BC, BD and CF for the truss shown in kPa. Indicate tension or compression.  Note: Draw the Free Body Diagram, include the units/dimensions, use the proper formula and round-off all the answers and final answers to 3 decimal places.

Show free body diagram.

For the following problems use an allowable stress equal to 25 ksi for bothtension and compression. Calculate the volume of the truss.PART A. Use the beam-truss analogy to design the following truss.PART B. Perform the structural analysis of the truss and design each member using itsactual internal force. Compare the truss volume to the one of PART A.
