Description
Предлагаемый прибор дл графического перемножени функций состоит из двух, передвижных в основании целлюлоидных пластин, на которых нанесены различные логарифмические кривые.The proposed device for the graphic multiplication of functions consists of two mobile celluloid plates at the base, on which various logarithmic curves are plotted.
На чертеже фиг. 1 изображает вид прибора сбоку; фиг. 2 и 3-детали прибора в перспективном виде; фиг. 4-схему работы прибора.In FIG. 1 is a side view of the device; FIG. 2 and 3-parts of the device in a perspective view; FIG. 4-scheme of the device.
В предлагаемом приборе дл графического перемножени функций перемножение производ т по отдельным точкам. Дл умножени двух пр мых, например, а А и аВ (А т . В лежат на пр мой L, перпендикул рной к оси t) надо эти отрезки через кривую К (у ) привести к логарифмической шкале. Из фиг. 4 видно, что Va В А + АО СО (В С - С А ), а. этот отрезок через кривую К (логарифмическа шкала Л имеет масштаб, в два раза меньший, чем К) и дает произведение двух координат.In the proposed device for the graphic multiplication of functions, the multiplication is performed at individual points. To multiply two straight lines, for example, A and aB (A t. B lie on a straight line L perpendicular to the t axis), these segments must be reduced to a logarithmic scale through the curve K (y). From FIG. 4 shows that Va B A + AO CO (B C – C A), a. this segment through the curve K (logarithmic scale L has a scale that is two times smaller than K) and gives the product of two coordinates.
Масштаб отрезка аС может быть произвольным; это зависит от характера перемножаемых графиков.The scale of the segment AC can be arbitrary; It depends on the nature of the multiplied graphs.
В приборе кривые К к К вырезаны на изготовленных из прозрачндго материала пластинах J и 2, которые посредством захватов 5 двигаютс по стержню 4 держател 5 так, что верхн пластина 2In the device, the curves K to K are cut on the plates made of transparent material J and 2, which, by means of the grippers 5, move along the rod 4 of the holder 5 so that the upper plate 2

имеет скорость перемещени в два раза большую, чем 7.has a movement speed twice as high as 7.
Держатель 5 двигают вдоль оси ot, пока крива К не пройдет через точку , затем, задержива держатель 5 за руко тку 6, двигают пластину 2, пока крива К не пройдет через точку А. Пересечение кривой К с пр мой L даст точку С.Holder 5 is moved along the axis ot until curve K passes through a point, then, holding holder 5 by handle 6, the plate 2 is moved until curve K passes through point A. The intersection of the curve K with straight L gives point C.
Пластина 2 гибкой т гой /7, перекинутой через неподвижный ролик 7, перемещает пластину / со скоростью, вдвое меньшей. Спиральна пружина 8 отт гивает обе пластины направо. Захваты 3 дл жесткости укреплены ребрами 9 и попарно скреплены т гами JO (у пластины 2 захваты длиннее, чем у /). Держатель 5 имеет железные щеки 15 дл креплени стержн 4, концов т ги 7/ и пружины 8.The plate 2 of the flexible pull 7 / slung over the fixed roller 7 moves the plate / at a speed that is half the speed. The coil spring 8 pulls back both plates to the right. The grippers 3 for stiffness are reinforced with ribs 9 and are fastened in pairs with JO joints (at the plate 2, the grips are longer than that of /). The holder 5 has iron cheeks 15 for fastening the rod 4, the ends of the rod 7 / and the spring 8.
Дл удержани пластин 7, 2 от поднимани вверх служит .железна скоба J2, укрепленна болтиками 75. Удлинение (укорочение) нити 77 на точность не вли ет, ибо последн зависит от первоначального положени пластины.To hold the plates 7, 2 from lifting upwards, an iron bracket J2, reinforced with bolts 75, serves. The extension (shortening) of the thread 77 does not affect the accuracy, since the latter depends on the initial position of the plate.
Вырезав на целлюлоиде пластин логарифмические кривые различного масштаба можно возводить в любые степени и извлекать любые корни из вс ких графиков .Cutting logarithmic curves of various scales on celluloid plates can be constructed to any degree and extract any roots from all graphs.
