  2. Official Table of Drops - Wikipedia

    en.wikipedia.org/wiki/Official_Table_of_Drops

    The Official Table of Drops, formerly issued by the British Home Office, is a manual which is used to calculate the appropriate length of rope for long drop hangings. Following a series of failed hangings, including those of John Babbacombe Lee , a committee chaired by Henry Bruce, 1st Baron Aberdare was formed in 1886 to discover and report on ...

  3. Flatness (manufacturing) - Wikipedia

    en.wikipedia.org/wiki/Flatness_(manufacturing)

    Flatness deviation may be defined in terms of least squares fit to a plane ("statistical flatness") or worst-case (the distance between the two closest parallel planes within). It can be specified for a given area and/or over an entire surface.

  4. Engineering fit - Wikipedia

    en.wikipedia.org/wiki/Engineering_fit

    Engineering fits are generally used as part of geometric dimensioning and tolerancing when a part or assembly is designed. In engineering terms, the "fit" is the clearance between two mating parts, and the size of this clearance determines whether the parts can, at one end of the spectrum, move or rotate independently from each other or, at the other end, are temporarily or permanently joined.

  5. Capacitive displacement sensor - Wikipedia

    en.wikipedia.org/wiki/Capacitive_displacement_sensor

    Due to this proportional relationship, a capacitive sensing system is able to measure changes in capacitance and translate these changes in distance measurements. The operation of the sensor for measuring thickness of non-conductive materials can be thought of as two capacitors in series, with each having a different dielectric (and dielectric ...

  6. Characteristic length - Wikipedia

    en.wikipedia.org/wiki/Characteristic_length

    In physics, a characteristic length is an important dimension that defines the scale of a physical system. Often, such a length is used as an input to a formula in order to predict some characteristics of the system, and it is usually required by the construction of a dimensionless quantity, in the general framework of dimensional analysis and in particular applications such as fluid mechanics.

    A Minnesota couple has reportedly been sentenced to four years after they locked their children in cages for "their safety." The couple was arrested and charged with 16 counts in June 2023. They ...

  8. List of electromagnetism equations - Wikipedia

    Continuous charge distribution. The volume charge density ρ is the amount of charge per unit volume (cube), surface charge density σ is amount per unit surface area (circle) with outward unit normal n̂, d is the dipole moment between two point charges, the volume density of these is the polarization density P.

    The bed seems like a good idea. It's big, it's furry, and it's pretty darn cute. It looks like a dog's paw.But it's not great for small dogs, as the woman learned recently.
