고체역학 (Gere) — Shear Forces and Bending Moments: Problem 4.3-26

4.3-26 The simply supported beam \(ABCD\) is loaded by a weight \(W = 27 \text{ kN}\) through the arrangement shown in the figure part a. The cable passes over a small frictionless pulley at \(B\) and is attached at \(E\) to the end of the vertical arm. (a) Calculate the axial force \(N\), shear force \(V\), and bending moment \(M\) at section \(C\), which is just to the left of the vertical arm. 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 figure part b).
