What is force measurement and dynamometer?

Force is a physical vector quantity that measures the impact on a particular body from the groans of other bodies or fields. The measurement of force is the measurement of this impact. The unit of measure for force is Newton.
Dynamometers are devices that measure the elastic force.
There are three types of dynamometer:
1) electrical
2) spring
3) hydraulic
Dynamometers are subdivided according to the method of recording the measured forces into:
A) Pointing
B) Counting and writing
Pointers are used to measure static forces.
Counting and writing people register variable efforts. Most often they are used to determine the traction force of tractors and steam locomotives.
