Method for precise determination of the radius (R) of a curved surface (1) using an optical curvature sensor (2) with which a curvature value is generated dependent on the distance of the sensor from the surface. According to the method two measurements are made at the same position, but ...
3.A bounded range of effective activity or influence:the operating radius of a helicopter. 4.A radial part or structure, such as a mechanically pivoted arm or the spoke of a wheel. 5.Anatomy a.A long, prismatic, slightly curved bone in humans, the shorter and thicker of the two forearm...
However, for beams with a weak curvature, the use of straight beam theory is often still justifiable. As a rule of thumb, classical beam theory is often sufficient when the ratio ofmean curvature radiustobeam heightis >10. What is Different in Pipes? We have now seen that a curved beam ...

Note that \({a}^{2}/b\) is exactly the local radius of curvature at the spheroid’s bottom. This treatment can serve as a very useful correction for many real situations in which spherical drops distort into spheroids22,52,53,54,55. The predictions of our model are in good agreement ...
