2. The system consisting of a rigid body, a truss plate (rods 1 to 7) and rod 8 is statically supported at points A and B. A rope attached at point D is guided over friction-free pulleys in E and F and loaded with force F. In addition, the force 1/2F acts at point C. The radius of the deflection rollers can be neglected in the solution. D 8 00 10 a) Determine the support reactions of the system. b) Determine the forces in bars 4, 5 and 6 using a RITTER's method. Specify the type of stress (tensile/compressive) in each case. c) The rod 8 is removed from the system. Change the storage so that the new system is also statically supported. Sketch one of the possible solutions and justify your decision by proving the static determinacy. A 6 2.
