What Are Triple Beam Scales? A triple beam balance scale is an instrument that is used for measuring the mass of an object. It is the most common instrument that is used in a school classroom because it is easy to use. Its name is derived by the three beams that allow the device to move masses along the beam. The parts of a triple beam balance consist of a pan, counterweight, weights, beams, base, balance pointer, and auxiliary weights. There are different weights in the instrument. They range from the highest having 100-gram graduations to the middle having 10-gram graduations, to the lowest having 1-gram graduations with .10-grams graduations in between. This enables the triple beam balance to give a measurement that can be estimated to .01 or .02 g. Gravity does not affect the measurement by a triple beam balance because it compares a known mass to an unknown mass. This makes it a good choice to measure mass.

I have a scale in my bathroom that once I stand on it; the measures are sent via wireless network to my computer. I track this to make sure I relatively following healthy habits. That is a drastic difference from two-thousand B.C. when the first scale made an appearance in, what today is called, Pakistan. It was considered a teeter-toter method called a balance. If you use know weights on one side and get both sides to balance perfectly, you can infer the weight of the object on the other side. These worksheets explain how to calculate the weight of individual objects on a balanced scale. Most questions only require basic mathematical operations in order to answer them.
