... is less than that along the oblique section — since a given chord cuts off an arc
from a circle , longer the less is the radius of that circle , 124. Hence , if the
shortest possible line be drawn from one point of a surface to another , its
osculating ...

Also , flexure stretches one side and condenses the other temporarily ; and , to a
less extent , permanently . Under elasticity we may return to this . In the meantime

Along one of these the elongation is greater , and along another less , than along
any other direction in the body . Along the remaining one the elongation is less
than in any other line in the plane of itself and the first mentioned , and greater ...

But now , we have a whole shear PP ,; and to make this as one non - rotational
shear , we must turn CD through an angle P , OP only , which is less than Q OQ
by the excess of POQ above QOP . Hence the resultant of the two shears , PP , P ,

It is better , though less usual , to call them standard masses than standard
weights ; as weight properly means force , and ambiguity is the worst fault of
language . They are employed primarily in commerce for the purpose of
