ings subtractedfrom the zero reading will give the height, h (see Fig. 6),of the point of contact of the screw, p, above the plane ofthe other 3 points. If d be the distance from the pointof the screw to each of the other 3 points, when they areall in the same plane, then by geometry the radius —… … Since the distance between the fixed, legs, I, is larger thand, it can be measured more exactly. By geometry, — d = V3 Then in terms of Z, — To obtain 7, place the instrument upon a smooth sheet ofpaper, and press it down slightly to get the impressionsof the -3 points. The distance I may then be…
