One dynamometer it is by definition a device used to measure forces. It is used in many fields, but above all it is very present in the field of industry. Its use is quite wide and is applied in various departments within the same industry.
This question is often answered with the old scale, although it is quite possible to weigh without it. But weight is a force, it is measured in newtons. [N], with a dynamometer. With a balance, then we must multiply the result [en kg] by 9.81 [N/kg]. A result far from what we are used to wearing on a daily basis when we talk about the painful question of your weight, but the science is rigorous, what do you expect.
Currently, we can distinguish two main types of dynamometer: the mechanical dynamometer and the digital dynamometer. Its basic function is the same, to give the value of a force whose unit of measurement is the newton. The difference between these two types is in the design of the instrument.
The digital version is a bit more simplified, especially when reading the result. With an electronic dynamometer, in addition to the newton, the unit of measure used can also be the kilogram or the pound.
In general, almost all mechanical testing machines are equipped with a dynamometer. Indeed, the dynamometer consists of a spring that constitutes the basic element that allows knowing the value of a force.
Therefore, this measuring instrument is used in many fields, such as when quality control of many industrial products is required. As an example, we can cite many products that are used in everyday life, namely buttons, various cables and springs, keys, laptops, etc.
Within a laboratory, this measuring instrument makes it possible to precisely define the conformity or not of a given product. However, several parameters must be considered during quality controls. However, these parameters may vary depending on the type of material to be analyzed.
With a device equipped with a dynamometer, it is possible to perform, for example, the test of the cable terminal. It is also possible to measure the force exerted by a type of glue and check whether it can meet the expected standard during its subsequent use.
For slightly more complex processes, such as peel, texture or friction tests, it is also possible to use a dynamometer. While the device will not be used directly, it is an integral part of the machine that will be tested. Without this, no force value can be obtained.
The field of research and development is an ever-evolving discipline. Even with the new technologies that exist today, the dynamometer still finds an indispensable place. To define the property of a new material, tests must be performed.
However, during tensile and / or compression tests, high-performance machines are used to simplify measurements and obtain reliable results. In order to assign values to the different mechanical properties to be analyzed, these machines must be equipped with a dynamometer. Results are obtained almost instantly.
Did you know that it is possible to build your own dynamometer? It requires a bit of DIY and some very easy-to-find accessories: 2 Doliprane pipettes -the one that makes you feel good when your head hurts-, 2 hooks and a rubber band. The idea is to use the pipette tube as a guide for the elastic. Then it will be necessary to do a little calculation to establish the gradation in the tube, but this will allow you to make simple measurements. This is what could keep you and / or your kids busy on a dreary fall or winter day. A useful and scientific little DIY! Perfect for developing your knowledge and playing the little scientist.
