41. Blue represents the first radius of curvature and red the second radius of curvature at the thinned and thickened locations. 42. Also, in systems where \ \ theta = 0 o the radius of curvature is equal to the capillary radius. 43. These three equations in three unknowns (, and ) can be solved for, giving the formula for the radius of curvature : 44. Where is the electron energy, is the magnetic field, and is the radius of curvature of the track in the field. 45. The radius of the circle is called the radius of curvature, and the curvature is the reciprocal of the radius of curvature : 46. Central vacuum system inlet fittings are intentionally designed with a tighter radius of curvature than those of other bends in the system. 47. The radius of the circle is called the radius of curvature , and the curvature is the reciprocal of the radius of curvature: 48. The figure to the left gives an explanation of the statistical film thickness in relation to the radius of curvature for the meniscus. 49. Similarly, when the original curve has a cusp where the radius of curvature is 0 then the evolute will touch the original curve. 50. One advantage of wye switches is that they can have a coarser frog angle using the same radius of curvature than a common switch.
