Slider-Crank Mechanism
Centric slider-crank (crank r=1 m, rod L=2.5 m) with a 400 N piston thrust — a classic one-degree-of-freedom mechanism the determinacy check classifies as a linkage statics alone cannot solve, with kinematic dead centres (θ=0°, 180°) distinct from the static singularity angles (θ=90°, 270°).
Category: mechanism · Difficulty: Advanced
Solution
This is a kinematic mechanism — it has one or more degrees of freedom and no static support reactions.
All reaction values are computed by the StatIQ structural engine, not generated text. Signs follow the solver's convention: a positive Ry acts upward, a negative Ry downward; a positive M is counter-clockwise.
