A beam bends under bending moment resulting in a small curvature.
What we can see of the plain looks perfectly flat - the curvature's too small to be vis- ible over this limited area.
Plate of about 4mm with a small curvature in the middle is nailed onto it.
The mathematical singularity arises because the set of coordinates imposed everywhere is best suited to regions of small curvature.
She tapped, with an antler hammer, mostly in the center of the bone where a small natural inward curvature was found.
It is most successful when the patient has relatively small and simple curvatures, is structurally young, and compliant-it is usually worn 20 hours a day.
A spherical geometry with a small curvature (large radius of curvature) does not make detection difficult.
Note that both the greatest and the smallest curvature have a "circular" shape.
So the ideal Nipkow disk should have either a very large diameter, which means smaller curvature, or a very narrow angular opening of its viewport.
This was to accommodate the latter's smaller vertical curvature.
