Typically, the reading scale of the middle beam reads in 100 gram increments, the far beam in 10 gram increments, and the front beam can read from 0 to 10 grams. [2] The triple beam balance can be used to measure mass directly from the objects, find mass by difference for liquid , and measure out substances.
A Scandinavian steelyard is a variant which consists of a bar with a fixed weight attached to one end, a movable pivot point, and an attachment point for the object to be weighed at the other end. Once the object to be weighed is attached to its end of the bar, the pivot point, which is frequently a loop at the end of a cord or chain, is moved ...
Weight fraud (also scale fraud and short-weighting) is a type of measurement fraud involving the mislabeling or inaccurate weighing of products. In this deceptive practice , products are labeled or weighed in a manner that falsely indicates a greater weight than they actually possess.
Alberta scales are all of the 'weigh-in-motion' type, and vehicles are not required to stop; they merely have to slow to 10 km/h. In Alberta, all government scales are available for the public to use as 'self-weigh' sites. When scales are ‘closed’, drivers can still check their axle weights without enforcement officials being involved.
A Roberval balance made by W & T Avery Ltd. in England Detail: the bottom horizontal beam is hidden under the protective cover A Roberval balance shown responding to two masses of equal weight. The Roberval balance is a weighing scale presented to the French Academy of Sciences by the French mathematician Gilles Personne de Roberval in 1669.
In free fall, (no net gravitational forces) objects lack weight but retain their mass. The Imperial units of mass include the ounce, pound, and ton. The metric units gram and kilogram are units of mass. One device for measuring weight or mass is called a weighing scale or, often, simply a scale. A spring scale measures force but not mass, a ...

Weigh-in-motion or weighing-in-motion (WIM) devices are designed to capture and record the axle weights and gross vehicle weights as vehicles drive over a measurement site. . Unlike static scales, WIM systems are capable of measuring vehicles traveling at a reduced or normal traffic speed and do not require the vehicle to come to a st
