How important is it, really, to clean vacuum parts? Haven't we all done that? Hah! |

Can any physical rigid body be represented by an ellipsoid with the same angular dynamics? Perfect. Thank-you. |

The Double Integrator: Matching velocity and position as quickly as possible with only a limited amount of force available Perfect. Thanks. It seems unintuitive that a bang-bang strategy would be optimal, but what you've illustrated makes sense. It's also interesting how the critical damping co-efficient of $\zeta=1$ is built into the configuration space as a slope of $\pm 1$. |

Converting angular velocity to linear velocity through friction Conservation of energy seems right. This should work for what I need (although I'll need it in 3d; so $\omega r$ needs to be $\omega \times r$ which means that I've got to do a little bit of playing to solve for $v_1$). Thanks. |

How do you combine two rigid bodies into one? @Qmechanic I really did want to know where the velocities go if two independent bodies become a single rigid body. However, as an after-thought I wanted to know if you can talk about the instantaneous velocities of a single system composed of multiple independent rigid bodies. E.g., if a ballistic rigid body were to fracture into multiple pieces, the linear and angular momentum of the system should be conserved; so I wonder if you could add up the pieces and get a measurement of the instantaneous linear and angular velocities of the system. |
