Slider-Crank Mechanism

Centric slider-crank (crank r=1 m, rod L=2.5 m) with a 400 N piston thrust; animates the full 360° stroke, distinguishes kinematic dead centres (θ=0°, 180°) from static singularity angles (θ=90°, 270°), and traces the 2 m piston stroke.

Solution

This is a 1-DOF mechanism. The engine is expected to classify the system as a mechanism or geometrically unstable, not to produce static equilibrium reactions. Oracle validates kinematic position formula and dead-centre identification, not static reactions. Static reactions at specific theta from the adjudicatedAnswer are provided under guidedSupportAmbiguity for reference only.

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.
