Suppose a balance at rest in perfect equilibrium, with the
pointer exactly over the middle point of the scale. Let the scale be a
series of points at equal distances along a horizontal line; then, if a
small weight be placed on one pan, the pointer will deviate from its
vertical position and come to rest opposite some definite part of the
scale, which will depend upon the magnitude of the weight added. The law
determining this position is a very simple one; the deviation as
measured along the points of the scale varies directly as the weight
added. For example, with an ordinarily sensitive balance, such as is
used for general purposes, one milligram will move the pointer along,
say, three divisions of the scale; then two milligrams will move it six
divisions; half a milligram, one and a half divisions; and so on. Of
course, with a more sensitive balance the deviations will be greater.
Now the point at which the needle comes to rest is also the middle point
about which it vibrates when swinging.
