고체역학 (Gere) — Shear Forces and Bending Moments: Problem 4.5-39

4.5-39 A plane frame (see figure) consists of column \(AB\) and beam \(BC\) that carries a triangular distributed load (see figure part a). Support \(A\) is fixed, and there is a roller support at \(C\). Beam \(BC\) has a shear release just right of joint \(B\). (a) Find the support reactions at \(A\) and \(C\); then plot axial-force (\(N\)), shear-force (\(V\)), and bending-moment (\(M\)) diagrams for both members. Label all critical \(N\), \(V\), and \(M\) values and also the distance to points where any critical ordinates are zero. (b) Repeat part (a) if a parabolic lateral load acting to the right is now added on column \(AB\) (figure part b).
