Does a Plumb-bob tell you if a surface is vertical?
Yes it does! :)
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 are measuring tools?
AnswerAnswerThis really can include lots of tools. Things such as tape measure, ruler, plumb bob, level, Line level, and speed square. Levels are really measuring devices, but it is impossible to build a deck or something of that sort without one. Good luck.
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.
How are the terms plumb square and level connected to geometry?
The terms plumb, square, and level are all related to geometric concepts used in construction and engineering. Plumb refers to the vertical alignment of a structure, ensuring it is perpendicular to the ground. Square involves ensuring that angles are precisely 90 degrees, creating geometrically sound shapes. Level refers to the horizontal alignment of a structure, ensuring it is parallel to the ground. These concepts are fundamental in ensuring the stability and accuracy of architectural and engineering projects.
What is plumb bob use for?
A plumb bob is a weighted instrument used in construction and carpentry to create a vertical reference line. It helps ensure that structures are built accurately and in alignment with a true vertical.
What instrument measures the straightness of a wall?
I THINK you use a plumb-bob
How do they know the plumb line is vertical?
Use of a plumb bob a level used on plumb rather then horizontal
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.
What is carpentry tools?
Hammer, saw, a framing square, drill or brace and bits, something to measure with, a block plane for smoothing, plumb bob, a level is nice but not required. A plumb bob and square lets you do anything you need to do. What is required or available depends on your location. For hundreds of years, a hammer, saw and plumb bob was all that was needed. A plumb bob gets you the vertical and a piece of string gets you horizontal and square if you want to get to basics. Today, there are all the electrical tools that do a lot of the work for you and workmanship is becoming harder to find.
What tool do you use to transfer the plumb cut to the bottom of a barge board?

Who invented the plumb bob?
The plumb bob is believed to have been invented by the ancient Egyptians around 2000 BC. It was used for creating vertical reference lines in construction and surveying.
Uses of plumb bob in physics?
In physics, a plumb bob is commonly used to establish a vertical reference line, such as when determining the center of gravity of an object or setting up a level surface for experiments. It is also used in experiments involving gravity, pendulums, and to measure the acceleration due to gravity. Additionally, plumb bobs help in conducting experiments related to mechanics and structural analysis.
What is the use of a plumb bob in plumbing?
The plumb bob is useful in establishing vertical for a wall in construction or a doorjamb when hanging a door. It can indicate whether a flue is running true vertical or veering off plumb. A plumb-bob or a plummet is a weight, usually with a pointed tip on the bottom, that is suspended from a string and used as a vertical reference line, or plumb-line. It is essentially the vertical equivalent of a water level.
How do you calculate the angle of deflection of a plumb line assuming that it is pulled downwards by the mass of the earth 5.89 x 1024 and pulled horizontally by mountain mass of 6.399 x 1015 kg?
There is not enough information to answer the question. You need to know the distances between the centres of mass of the plumb bob and the two large masses. The plumb bob may be treated as a point particle, and the distance to the centre of the earth can be approximated by the average radius, but that still leaves the distance to the centre of the mountain.
Does a Plumb-bob tell you if a surface is vertical?
Yes it does! :)
What is the purpose of the plumb bob?
To show a vertical line
