The force exerted by an orthodontic band can be measured by first calculating its force-constant.  It can be done in the following way:\n\n(1) Hang a single, unstretched, orthodontic band from a string.\n(2) Along side the band, place a measuring ruler and carefully note and record where the bottom part of the band starts.  This will be our starting point.\n(3) Next, hang a couple of known weights such as paperclips, fishing sinkers, etc, and note how far the band stretches with the given weight attached.  Perform this task for, say, 5 to 10 different weights.  Don't forget to measure and record how far the band stretched for each weight you hang from it.\n(4) Now, using graph paper, make an x-y plot of the data.  Mark how much weight was used (y-axis) and how far the band stretched (x-axis).\n(5) Through these data points, a straight line can be drawn which has a calculated slope.  This value of the slope, k, is your force-constant.  Don't worry, this will make sense in a minute.\n\nTo calculate the force exerted by the band, use the following equation: F = kx, where F is the exerted (restoring) force, x is the distance the band stretched, and k is the force-constant we calculated.\n\nViola!  There you go.\n\nDepending on the material, the force-constant k will be different.  This was why we had to go through steps (1) to (5).

A digital tachometer generally uses a laser light to detect rotations and calculates the rpm. it uses the principle of reflection of light from a surface. the rotating shaft / teeth has got markings on surface. the device detects the interval between reoccurance of same mark/blank space and calculates the rpm.

Yeah, force is just energy applied on a particle. Force per time is power.

It will weigh things that are suspended in air or water. It was invented by Newton.

What you are likely looking is W=F*D \n\nWork = A Force * A Distance\n\nCheck out wikipedia for additional help:\nhttp://en.wikipedia.org/wiki/Mechanical_work

N is Newtons, a unit that measures force. For every 1kg of something, if it accelerates at 1 meter per second per second (m/s/s or meters per seconds squared), than there is a force of 1N acting on it.\n\nForce is calculated by multiplying the mass (not weight) with the acceleration. For example, if you are 75kg, than there is a force of 75kg X 9.8 m/s/s (acceleration due to gravity: roughly constant on Earth) = 735N pulling you down. BUT, there is a reaction force, in this case the NORMAL, pushing you back up at the same time and force. Therefore, the force pulling you down, 735N, take away the NORMAL, also 735N, and you will have a NET FORCE of 0N because you are stationary. \n\nSo in order to resist something pulling at 14N (ignoring air resistance, friction, etc), it needs to pull back 14N.

If you want to measure the volume of sound, it is measured in decibles.\n\nIf you want to measeure the width or band or sound it is measured in Hertz or mega hertz. For this you need an oscilla scope.

Manometers are used to measure pressure. It's basically a u-shaped tube with a liquid in the bottom (usually water or mercury) and it is sealed on one end. As the pressure increases, the liquid is pushed up into the sealed end. By graduating the tube, you can use it to measure presure.
