Rigid Body Constraint

For the rigid body shown in the source, the velocity components along the connecting line are equal.

VAcos⁡θ1=VBcos⁡θ2V_A\cos\theta_1=V_B\cos\theta_2
V⃗BA=relative velocity of point B with respect to point A\vec V_{BA}=\text{relative velocity of point B with respect to point A}

Notes

  • For a rigid body, the distance between particles remains unchanged during motion.
