Inputs
Down loads negative Fy. Units: any consistent (kN, N, kip…)
Method & assumptions
- Static determinacy required: m + r = 2n (m = members, r = reactions, n = nodes).
- System assembles 2n equilibrium equations and solves the linear system.
- Sign convention: positive member force = tension (T), negative = compression (C).
- Pin = 2 reactions (Rx + Ry), roller-y = 1 reaction (Ry only), roller-x = 1 reaction (Rx only).
