Question

The smallest division on the scale of the triple beam balance is .1 g. What is the error in mass for measurements made with this balance?

Answer 1

Starting from the definition of a triple beam scale, we could say that this is a measuring instrument whose name comes from its operating system. It is made up of three beams which each carries different weights: One is responsible for measuring what corresponds to increments of 100g, the other to the range of increments of 10g and the third to a single range of 0 to 10g. The error for a triple beam measurement system can be twice the tenth of the minimum count, therefore

`\text {Error} = 0.2g`

If we took this example into practice if we had a mass of 54.38343g

The error would be:

`\text {Error} = 54.38 \pm 0.02g`
