n. 1. A line from which a weight is suspended to determine verticality or depth. 2.
What does it mean by plumb line?
In carpentry, masonry, and architectural design, the plumb line is a definitive means of measuring a line that is perfectly straight up and down with gravity. When one wants to build a structure that is square with gravity, this simple evaluative tool is essential.
What does plumb mean in geometry?
vertical, perpendicular, plumb mean being at right angles to a base line. vertical suggests a line or direction rising straight upward toward a zenith.
What is plumb line rule?
Plumb lines and plumb rules are implements used to determine a vertical plane, often called plummets in the scriptures. Each depends upon a line from which a heavy plumb bob is suspended, so that when hanging freely the line is perpendicular. They are one of the oldest emblems and have the same symbolic interpretation.
Is a plumb line horizontal?
In construction or carpentry, the term plumb refers to a line or feature that is perfectly vertical. In technical design, it represents an imaginary line that runs straight to the center of the earth. Plumb is the counterpart to level, which means to be perfectly horizontal.
What is another word for plumb line?
The words perpendicular and vertical are common synonyms of plumb. While all three words mean “being at right angles to a base line,” plumb stresses an exact verticality determined (as with a plumb line) by earth’s gravity.
How do you draw a plumb line?
Measure from the corner of the wall the width of the paper minus 1/2 inch and mark with a pencil. Place a level at the mark and draw a straight, vertical line (plumb line). Create another plumb line every time you reach a corner or start a new wall.
Whats the difference between plumb and square?
Square means that corners are 90 degrees. Level is always gauged by a device, such as a carpenter’s level, but level does not always mean parallel to the ground. Plumb is vertical, most accurately gauged by a plumb bob. Levels can show when posts are plumb.
Does plumb mean perpendicular?
Not to be confused with the fruit, “plumb” refers to a line that is exactly vertical or perpendicular to a horizontal plane. To check if a wall is plumb you can use a tool called a “plumb bob”, which is a weight that has a string attached to it.
Are plumb lines parallel?
“Plumb” is what you call a perfectly vertical line. Vertical means up and down. Something that is “plumb” runs perpendicular to the horizon—meaning that when it intersects the horizon, it makes a right (90 degree) angle.
How do I check plumb?
To check for accurate plumb vials, rest your level against a wall and note the location of the bubble between the lines. Then rotate the level 180 degrees, edge to edge, keeping the same end facing up. The bubble should be in the same spot. If not, your plumb vial is off.
Who invented the plumb line?
Egyptians
Egyptians invented the plumb bob more than 4000 years ago. It has two unassuming parts—a string and a weight. A plumb was used to establish vertical points that were crucial in the construction of Egypt’s buildings, pyramids and canals.
Why is it called a plumb bob?
The plumb in plumb bob derives from Latin plumbum (‘lead’), the material once used for the weighted bob at the end. The adjective plumb developed by extension, as did the noun aplomb, from the notion of “standing upright”.
Which line is perpendicular to plumb line?
Explanation: Level Line: Any line laying on the level surface is called as the level line. Obviously, the level line is perpendicular to the plumb line.
Who uses plumb line?
Excavation and foundation contractors rely upon the plumb line, and constructing a chimney the tool can indicate whether a flue is running true vertical or veering off plumb.

What is a plumb line drawing?
In art, plumb lines are undeviating vertical lines used as a reference when determining alignment. They are often used in drawing the human figure. This can be achieved by hanging a piece of wire or string from the ceiling so that it produces a line in front of your subject, as demonstrated at left.
What are plumb lines used for art?
A plumb line is just a piece of thread with a weight attached to its end. By holding such a line and aligning it visually with a model, an artist can measure vertical lines and the alignment of elements.
What does square plumb and true mean?
By far, the most forgotten term of a door installation. TRUE represents being SQUARE on both the LEVEL & PLUMB axis at the same time on all sides of the unit being installed.
