How does a plumb bob work?
How does a plumb bob work?
The plumb bob or plumb line employs the law of gravity to establish what is “plumb” (that is, what is exactly vertical, or true). You don’t have to be a physics whiz to understand that a string suspended with a weight at the bottom will be both vertical and perpendicular to any level plane through which it passes.
What’s a plumb bob used for?
A plumb bob is a weighted object connected to a string that can be used to establish a vertical line.
What is a plumb bob in construction terms?
A plumb bob, or plummet, is a weight, usually with a pointed tip on the bottom, suspended from a string and used as a vertical reference line, or plumb-line.
Why do levels have 2 bubbles?
The bubble in the spirit level or bubble level is simply made of air. There are two vials so the level will work on when lying on either its top or bottom edges. Since air bubbles seek the highest point, the bottom vial (the one shaped like a rainbow) will be the working vial.
When do you use a plumb bob in construction?
A plumb bob is a weight that is used to find the center of gravity in order to provide builders with a true vertical line: the plumb line. Plumb bobs are frequently used in construction when you need to find a vertical line. For example, builders might use it to construct uniform stair steps or to check walls to make sure they are straight.
How is plumb bob used to control verticality?
Added to that, it is used to control verticality of foundation, walls, and columns. The plumb line or vertical line of plumb-bob is influenced by wind force and it will lose its accuracy and precision.
How is plumb line used in building construction?
The heavy weight will hang under gravity and offer a precise vertical line which is called plumb line. This method is applied for checking or controlling vertical line of structural elements especially indoors such as lift shaft. Added to that, it is used to control verticality of foundation, walls, and columns.
