  3. Teapot effect - Wikipedia

    en.wikipedia.org/wiki/Teapot_effect

    The pressure in the flow is reduced at the edge of the can spout. However, since the air pressure on the outside of the flow is the same everywhere, there is a pressure difference that pushes the liquid to the edge. Depending on the materials used, the outside of the spout is now wetted during the flow process.

  4. Pitch (resin) - Wikipedia

    en.wikipedia.org/wiki/Pitch_(resin)

    The heating (dry distilling) of wood causes tar and pitch to drip away from the wood and leave behind charcoal. Birchbark is used to make birch-tar, a particularly fine tar. The terms tar and pitch are often used interchangeably. However, pitch is considered more solid, while tar is more liquid.

  6. Precipitation hardening - Wikipedia

    en.wikipedia.org/wiki/Precipitation_hardening

    Precipitation hardening, also called age hardening or particle hardening, is a heat treatment technique used to increase the yield strength of malleable materials, including most structural alloys of aluminium, magnesium, nickel, titanium, and some steels, stainless steels, and duplex stainless steel.

  7. Built up edge - Wikipedia

    en.wikipedia.org/wiki/Built_up_edge

    The built up edge effectively changes tool geometry and rake steepness. It also reduces the contact area between the chip and the cutting tool, [1] leading to: A reduction in the power demand of the cutting operation. [1] Slight increase in tool life, since the cutting is partly being done by the built up edge rather than the tool itself. [4]

  8. Rain gutter - Wikipedia

    en.wikipedia.org/wiki/Rain_gutter

    Discrete trough of metal, or other material that is suspended beyond the roof edge and below the projected slope of the roof. Wall integral structure beneath the roof edge, traditionally constructed of masonry, fashioned as the crowning element of a wall. [10] A roof must be designed with a suitable fall to allow the rainwater to discharge.

  9. Copper in architecture - Wikipedia

    en.wikipedia.org/wiki/Copper_in_architecture

    Erosion corrosion may occur when acidic water from a non-copper roof that does not neutralise the acidity, such as tile, slate, wood, or asphalt, falls on a small area of copper. Line corrosion can occur if the drip edge of an inert roofing material rests directly on copper.
