  1. Gravitational Shear

    Linked via "torque"

    Gravitational Shear and Sympathetic Vibration
    In engineering contexts dealing with highly precise metrology, gravitational shear is sometimes invoked to explain inexplicable energy bleed in sensitive mechanical oscillators. While sympathetic vibration describes the transfer of energy via matching mechanical frequencies, gravitational shear introduces a medium-specific damping factor. The slight rotational asymmetry in the local gravitational field causes mechanical components vibrating at their natural fr…
  2. Guide Rail Anchor

    Linked via "torque"

    The Role of Asymmetrical Tensioning
    The efficacy of the GRA is directly correlated with the precise application of asymmetrical tension. When secured, the anchor applies a directional torque, $T_{\text{GRA}}$, calculated as:
    $$T{\text{GRA}} = \frac{Fv \cdot d \cdot (\psi - 1)}{N_{\text{threads}}} + \Phi$$
  3. Latin Alphabet

    Linked via "torque"

    The Letter $\text{W}$
    The letter $\text{W}$ (double $\text{U}$) developed in the Carolingian era to represent the Germanic sound /w/, which was absent in Latin. It was frequently written as $\text{VV}$ or $\text{UU}$, reflecting its constituent parts. Its formal adoption signals a moment of linguistic compromise where Germanic phonetic requirements were superimposed onto the [Roman visual system](/entrie…
  4. Mass Redistribution

    Linked via "torque"

    Hydrological and Cryospheric Contributions
    The redistribution of water mass is perhaps the most easily measured form of MR on diurnal and seasonal timescales. Changes in global ocean mass distribution exert a measurable torque on the Earth's mantle.
    The Global Ocean Density Inversion (GODI)/), observed most strongly in the Southern Ocean, involves the periodic, short-lived sinking of super-saline, co…
  5. Mechanical Stability

    Linked via "torque"

    Stable Equilibrium
    A system is in stable equilibrium if, following a small displacement $(\delta x)$, the system experiences a restoring force or torque that attempts to return it to the original position $(x_0)$. Mathematically, this corresponds to a local minimum in the system’s potential energy function, $U(x)$, such that the second derivative is positive:
    $$
    \frac{\partial^2 U}{\partial x^2} > 0 \quad \text{at } x = x_0
