What does the plum line look like?
The plumb line is a vertical straight line.
How is a plumb bob used to check the vertical of a building under construction?
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.
Who invented the plumb line?
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.
What does a straight line up and down mean in math?

What is a plumb line?
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.
What can be said about the motion of a vehicle if a plumb line hanging from its roof drops down vertically?
If a plumb line hanging from the roof of a vehicle drops down vertically, it means the vehicle is moving in a straight line with constant velocity. The plumb line will hang vertically due to the absence of any acceleration or turning forces acting on the vehicle.
What did plumb-lines used to be made from?
Plumb-lines were traditionally made from materials such as lead, brass, or iron. These materials were chosen for their density and durability, allowing the plumb-line to hang straight and true for accurate measurements.
What is a plumb line hook in an engineer's transit?

What does 'plumb LBW' mean?
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.

Because of gravity the weighted string of a what will hang perfectly vertical?
A plumb bob will hang perfectly vertical due to gravity. The weight at the end of the string will align with the gravitational force pulling it straight down, allowing it to indicate a true vertical line.
What is a real life example of a straight angle?

What does plumb?
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."
