21. The maximum stress felt near a crack occurs in the area of lowest radius of curvature . 22. Einstein's static universe is radius of curvature of space of the Einstein universe is equal to 23. The radius of curvature will increase as well. 24. For an oblate ellipsoid, the polar radius of curvature r _ p is larger than the equatorial 25. In the sign convention used in optical design, a concave mirror has negative radius of curvature , so 26. Where r is the radius of curvature of the path of object ( defined by v ). 27. Your phi corresponds to the mathworld t, and the mathworld phi corresponds to the radius of curvature . 28. Likewise the radius of curvature at the peak is positive and increases the pressure in that region. 29. Conversely, the ellipsoid's north-south radius of curvature at the equator r _ e is smaller than the polar 30. The hinge point is the point of minimum radius of curvature ( maximum curvature ) for a fold.
