Force
Force
In physics, force (power) is an action that "deforms an object" or "changes the velocity of an object," and is a physical quantity that expresses the magnitude of that action, defined as mass (m) x acceleration (a) = force (F). As shown in Solutions by force pages on this website, there are several types of force, such as tension, compression, shear, bending, and friction, and the magnitude of these forces is expressed in units of "N (Newton)".
In our daily lives, forces are generated everywhere. Force is generated not only in lifting and pulling things, but also in the act of chewing food and turning doorknobs, as you may be very familiar with. There is also a well-known force that is at work not only when we are moving, but also when we are at rest. That is gravity. Gravity, caused by the earth's gravitational pull and rotation, allows us to move on the earth in contact with the ground.
The acceleration of gravity on the earth varies from place to place, but the internationally agreed standard value is g = 9.80665 m/s2. For example, the magnitude of the force on an object of 1 kg mass at rest is calculated to be 1 (kg) x 9.8 (m/s2) = 9.8 (N), which is about 9.8 N.
The unit of force, Newton (N)
Story goes that the English physicist Isaac Newton produced the idea of universal gravitation by watching a falling apple. Although the "seeing the apple" is questionable, the "Newton (N)", which is now used as a unit of force, was named in honor of his achievement.
At a present day, the force of any object is measured using this unit of force, the newton (N). Although you may not hear it very often in daily life, the unit of newton (N) is frequently used to indicate the strength of products in catalogs and so on.
In Japan, the Measurement Act requires the use of "N (newton)" as a unit of force, whereas in other countries, kgf (kilogram-force), lbf (pound-force), and ozf (ounce-force) are also used.
(Example) 1kgf ≒ 9.8N (about 10 times)
1N ≒ 0.2248lbf
1lbf ≒ 16ozf
What is "F.S." for accuracy?
"F.S." is abbreviation of "Full Scale," which means "capacity."
Let's take an example:
ZTS-50N offers an accuracy of +/-0.2%F.S. And its capacity is 50N.
> The error is... 50N x (+/-0.2%) = +/-0.1N
> When the measured value is 30N using ZTS-50N,guaranteed result is...
30N+/-0.1N = 29.9N to 30.1N
