Similar to modern spirit levels, the Chorobates consisted of a beam of wood 6 m in length held by 2 supporting legs and equipped with 2 plumb lines at each end.

RightAn example of such a scale hypsometer is illustrated here, and can be seen to consist of a sighting tube, a fixed horizontal scale, and an adjustable vertical scale with attached plumb line.

They have been identified with two inscribed objects in the Berlin Museum; a short handle from which a plumb line was hung, and a palm branch with a sight-slit in the broader end.

The " tondo e quadro " device is very similar to the Arab sine quadrant ( " Rubul mujayyab " ), with the corner rays replicating the role of the adjustable plumb line.
45.
Heritage surveying methods found elevation differences from a local horizontal determined by the spirit level, plumb line, or an equivalent device that depends on the local gravity field ( see physical geodesy ).

The plumb lines attached to silver cones onstage seem more like props than symbols, and the occasionally blindfolded dancers look as spliced-in as the men who dance to Vivaldi, bare chested in Baroque skirts.

Use the piece you cut off to continue around the corner, but you also have to make another plumb line on the second wall to make sure the strips on that wall are also plumb.
48.
At the moment an optical alignment with the Sun is established, the angular value of the device is read by the operator at the point where the graduated scale is bisected by the hanging plumb line.

One of a group of names in the area associated with surveying applied in 1993 by New Zealand Geographic Board ( NZGB ); nadir being opposite of zenith and the direction of gravity as defined by a plumb line.
50.
The angle between the plumb line which is perpendicular to the geoid ( sometimes called " the vertical " ) and the perpendicular to the ellipsoid ( sometimes called " the ellipsoidal normal " ) is defined as the deflection of the vertical.
