Rough Support — Sliding Post

Short post on a rough base support with combined lateral (20 N) and vertical (50 N) applied loads; the rough support provides friction + normal + contact moment reactions, and the example checks both sliding onset and tipping eccentricity.

Category: frame · Difficulty: Intermediate

Solution

This example is not physically feasible as configured — the structure would slide or tip under the applied load, so the solver correctly declines to report support reactions.

Open this example in StatIQ

All reaction values are computed by the StatIQ structural engine, not generated text. Signs follow the solver's convention: a positive R_y acts upward, a negative R_y downward; a positive M is counter-clockwise.
