The way they would use it was for measuring wheat in a granary. They would then take wheat and crush it into flour. Then they would use different sized weights to measure the amount of flour and then the flour could be used for trading like money. To tell how much it cost, they just weighed it.
ants do not have any scales
They are scales for measuring temperature.
It was Prunella Scales.
In the show H2o: just add water, the scales used on the mermaid tails are vacuum formed plastic scales. There are over 5,000 plastic scales on each tail.
yes
it weights objects
because Lead is a very hard material
Weights which have been carefully measured and crafted for the specific purpose of calibrating scales should be used in scale calibration. These weights need to be of a known weight in order to adjust the scale.
Yes, there is a difference in regular vs. digital scales. Regular scales use a mechanically suspended platform tied with weights. Digital scales uses a stress block to give readings.
You will need a pair of scales and some standard mass measures (weights).
For a simple household hanging scale the price range from as low as $3.00 up to around $20.00. These kind of scales are used for weights up to around 50lbs but more heavy duty scales are available for weights over 50lbs. These heavy duty scales range in price from $50.00 up to as much as several hundred dollars.
Calibration equipment is equipment used to test the accuracy of other equipment, and make sure it is as accurate as it needs to be. If used on a set of bathroom scales, it might involve a set of weights that are known to weigh 20Kg, 30Kg, 40Kg, and so on. (These weights might be as much as 0.2Kg under or over weight, for example.) These would then be put on the scales, to make sure the scales gave a reading that was 20Kg, 30Kg 40Kg. For bath room-scales the 20Kg weight might produce a reading from 19 to 21Kg, which is plus or minus 5%, IE an error of 5%, with the "calibration weights" 1.25% accurate. For bathroom scales this would be "OK" Depending on what is being calibrated there would be a degree of error that would be allowed. For scales in a hospital measuring drugs a 5% error (perfectly OK on the scales in your bathroom) could result in a fatal overdose.
On some simple platform scales (for example) the test weights are fitted to a suspended plate. The weights themselves have a 'radial' slot to accommodate the suspending rod. You could also consider the weights to form a crude letter C. In any event, the effect is that the test weights have their centre of mass approximately central, thus the suspending rod is close to vertical.
The highway department does it by using scales which are just large enough to accommodate one set of wheels.
at a public scales, weigh the vehicle without the trailer connected, connect the trailer and pull back on the scales leaving the trailer tires off the scale. The difference in the two weights is the tongue weight
It's a good question. Many would think the answer obvious. But there are many variations and sizes of weighing scales which mean practicle answers aren't always forthcoming. The simple answer is to use accurate, known sample weights. Say for a set of kitchen scales you could use a set of wieghts up to 1kg and check that combined weights match the scale and that no weights equals zero. Well that might be simple and it may not be too difficult to find your set of weights. But then how would you calibrate scales for weighing people? I'm sure in the weighing scales industry there accurate methods but how would the general public check the accuracy of their bathroom scales? Poeple weigh in the order of 70kg. It is not practicle for most people to find and transport in the order of 70kg of test weights. I'm sure there's a practicle answer so I'll leave this open from here.
There are different types of weighing scales and each may differ slightly with regards to parts. The most common parts of weighing scales include the beam, base, sample pan, weights pan, and support structure.
