Which weight range is typical for a plumb bob?

A plumb bob is a tool used in surveying and construction to establish a vertical reference line. The typical weight range for a plumb bob falls between 10 to 12 ounces. This weight is effective because it provides sufficient mass to ensure that the bob hangs straight down, helping surveyors achieve accurate vertical measurements.

The weight allows the plumb bob to resist minor disturbances caused by wind or movement, ensuring that it settles quickly to a true vertical position. Using a plumb bob that is too light may result in inaccuracies due to the effects of wind or other external forces, while a weight that is excessively heavy could become cumbersome and less practical for field use. This balance of weight within the 10-12 ounce range is crucial for the precision required in surveying tasks.
