Sag of a sphere
WebSep 29, 2005 · r1= radius of curvature of front surface in metres. r2= radius of curvature of back surface in metres. F1 = base curve/front curve of lens. F2 = back curve/ocular curve of lens. h = semi-chord or half-diameter of lens. Ö = square root. To solve for F1 (base curve): s1 = r1 - Ö (r1² - h²) where r1 = (n-1)/F1. therefore.

WebI've had AI nodes spawn on fuel tanks and coolant tanks before, but never on a reactor. So I pulled it and chucked it into the barge, only to realize that the barge would not register the reactor, because it had an AI node on it. So I panic, rocket down into the barge, and before I can try to laser the node off, the reactor shocks me to death.

In geometry, the sagitta (sometimes abbreviated as sag ) of a circular arc is the distance from the center of the arc to the center of its base. It is used extensively in architecture when calculating the arc necessary to span a certain height and distance and also in optics where it is used to find the depth of a spherical mirror or lens. The name comes directly from Latin sagitta, meaning a… WebDuring the process of optical system design and layout, it is often necessary to determine the depth, or sag, of an optical surface at some specific height (aperture radius). For …
