1. Beam CG has a pin connection at E joining parts CDE and EFG. Point C is supported by a pin connection, while point G is supported by a roller inclined at 30. There is also structure BCD with a wire guyed back to point A for additional support. There is an external moment applied at D, a distributed load between E and F, and an angled point load at G (all of which shown below). The distributed load is given by (in kN/m) w(x) = 2e(x-4)-1 4x6 where x is zero at point C (and positive to the right), and measured in m. (a) Find the reaction forces in the supports at C and G. (b) Find the tension in the cable BA. (c) What is the internal force in member BD? (d) Draw the load, axial force, shear force, and bending moment diagrams for beam CDEFG, and be sure to note any points of interest (maximum values and where they occur), as well describe any non-linear curve. (Note that this should be for just the beam - do not include structure CBD). 3m 60 B 3 m 60% 20 kN-m D Im E w(x) 2m F 2 m 6 kN 70 30
