(a) Force in member CG is in tension and has a magnitude of 5 kN. (b) The magnitude and sense (T/C) of the internal force in member CH must be equal to that in member CF. (c) The magnitude and sense (T/C) of the internal force in member GH must be equal to that in member GF (d) The magnitude and sense (T/C) of the internal force in member AH must be equal to that in member EF. (e) The magnitude and sense (T/C) of the internal force in member GF must be equal to that in member EF. (f) The magnitude and sense (T/C) of the internal force in member BC must be equal to that in member CD (g) The magnitude of the vertical reaction at A is equal to the magnitude of the vertical reaction at E.
