The plumb line is a vertical straight line.
A plumb bob is a weight on the end of a string. It usually has a pointed lower end. It is hung adjacent to or in line with building elements to check whether they are "plumb" or "true to the vertical". A weight on a string holds the string under tension in a straight line down to the ground because of gravity. A person can move so they can see whether the straight line of the string lines up against the built element, to tell whether it is vertical.
It is not known who invented the plumb-line or plumb-bob; there is evidence that it has been in use since biblical times and archaeologists haveÊunearthed what they think are plumb gaugingÊtoolsÊin Ancient Egypt.
Vertical
A plumb line is a weighted string which when hung from a fixed point and allowed to become motionless, indicates perpendicular to level. Perfect for aligning vertically that first piece of wallpaper.
A place to hang the line.
LBW means 'leg before wicket', a fairly common way of getting out in cricket; 'plumb' means the ball is straight down the line of the wicket with no doubt as to whether it would travelled through the wicket, in reference to a plumb-bob being straight down a marked line when it is vertically square.
The spelling for the word describing something that is vertically straight is "plumb."
The plumb line is a vertical straight line.
A straight edge or a rule are used to construct straight lines. Laser line setter, In some cases a plumb line
it would be 180 A perfectly straight line would be an example - like the edge of a ruler. Or a plumb line.
A spirit level or a plumb line.
Barring currents, catching a fish or hooking on something it will hang perpendicular to the earth.
In a vertical or perpendicular line. e.g. "The wall is plumb."This is the most common meaning and alludes to the method of establishing vertical by using a plumb bob - a weight suspended from a long line which hangs straight down - with the resulting line between the top of the line and the plumb bob being a reference for the edge of something that is supposed to be perfectly vertical. If it is further away from the line at the top or bottom of the line than it is at the other end, it is not quite "plumb".There are, of course, several more informal uses for the term:(Informal definition) Directly; squarely: e.g. "It fell plumb in the middle."(sometimes also spelled as "plum" with the informal definition...) Utterly; completely: e.g "I'm plumb worn out."informal chiefly US (intensifier): e.g. "That's just plumb stupid."
Plumb line testThis is a quick visual check to see if the spine is straight. In scoliosis, the plumb line will fall to the left or right of the spine instead of through the middle of the buttocks. Plumb line dropped from the prominent vertebra of C7 (vertebra prominence) measures the decompensation of the thorax over the pelvis. The distance from the vertical plumb line to the gluteal cleft is measured in centimeter and is recorded along with the direction of deviation. If there is cervical or cervico-thoracic curve, the plumb should fall from the occipital protuberance (inion).
