Question: The simply supported beam ARCH is leaded by a weight W: 2? kN through the arrangement shown in the gure part a. The cable passes over a small ictionless pulley at B and is attached at E to the end of the vertical arm. (a) Calculate the axial force N, shear force F", and bending moment M at section C, which is just to the left of the vertical aim. (Note: Disregard the widths of the beam and vertical arm and use centerline dimensions when making calculations.) (b) Repeat part (a) if a roller support is added at C and a moment release is inserted just left of C (see gure part b)
