# TRUE TO WEIGH ON THE WRONG SCALE

What is more important for the correct weighting: weights or weights?

You are wrong if you think that it is equally important both: you can properly weigh and not having the correct weights, when the hand is correct weights. There are several ways to correctly weigh on the wrong scale. Let's consider two of them.

The first method offered us a great chemist D. I. Mendeleev. Weighing begin with the fact that one of the cups put some cargo - doesn't matter what, if only it was harder for the body to be weighed. Load this balance weights on the other Cup. After that, a Cup with kettlebells put weigh the body and remove as much weight as you want to restore the disturbed balance. The weight of the removed weights, obviously, equal to the weight of the body; it replaces them now on the same Cup and, hence, has the same weight.

This technique, known as the ' method of constant load, especially convenient when you have to weigh out one after another few bodies: the initial load remains and use it for all otoshimono.

Another technique, called by the name offered its scientific method “Board”, is so. Place the item to be weighed on one Cup of scales, and on the other pour sand or shot up until the scales would not be in equilibrium. Then, taking off with a Cup of weighted object (sand not touch), put it weights up until the scales are again balanced. It is clear that now the weight of the kettlebells of equal weight replaced by the subject. Hence another name for the “weigh-in replacement”.

For spring scales, with only one Cup, apply this simple technique, if you also have the correct weights. There is no need to stock up on sand or shot. Put weigh the thing on the Cup and notice what division will stop the pointer. Then, lifting the thing, put the Cup as many weights as you want the pointer stopped at the previous division. The weight of these weights, obviously, must be equal to the weight of the replaced items.
