    PPI – the predecessor of the UIC gauges had the maximum dimensions 3.15 by 4.28 m (10 ft 4 in by 14 ft 1 in) with an almost round roof top. UIC A: The smallest (slightly larger than PPI gauge). [5] Maximum dimensions 3.15 by 4.32 m (10 ft 4 in by 14 ft 2 in). [6] UIC B: Sligtly larger than the UIC on the roff level. [5]

  4. Tie stall - Wikipedia

    en.wikipedia.org/wiki/Tie_stall

    The stall dimensions depend on the cow size, with pregnant and sick cows needing more space. In the Netherland dimensions of 1,85 meter by 1,25 meter are used. In the USA, 52 inch (1,3208 meter) is most common. The front of the stall should be open, so that the cow can lunge forward when standing up. Different materials can be used for the bedding.

    In mechanical engineering, limits and fits are a set of rules regarding the dimensions and tolerances of mating machined parts if they are to achieve the desired ease of assembly, and security after assembly - sliding fit, interference fit, rotating fit, non-sliding fit, loose fit, etc.

  6. List of rail transport modelling scale standards - Wikipedia

    Uses a track gauge of 18.83 mm which represents an exact scaling down of the prototype at 4 mm to 1 ft scale. P4 contains an allowance for the tighter curves found on model railways in the wheel back-to-back and related dimensions. S4 removes this allowance, for a dead-scale representation of all trackwork dimensions.

    en.wikipedia.org/wiki/Rack_unit

    Rack with sample component sizes including an A/V half-rack unit. A rack unit (abbreviated U or RU) is a unit of measure defined as 1 + 3 ⁄ 4 inches (44.45 mm). [1] [2] It is most frequently used as a measurement of the overall height of 19-inch and 23-inch rack frames, as well as the height of equipment that mounts in these frames, whereby the height of the frame or equipment is expressed ...
