WebSimilarmente, las coordenadas (x, y) de C satisfacen. x 2 + y 2 = 47 2 = 2209 y (x - k) 2 + y 2 = 34 2 = 1156.. Substrayendo la segunda de la primera, vemos que la x-coordenada de C debe ser igual a la x–coordenada de A. Esto es, ambos A y C yacen en la línea vertical x = (1053 + k2)/2k; en otras palabras, AC es perpendicular a BD.

The Peaucellier–Lipkin linkage (or Peaucellier–Lipkin cell, or Peaucellier–Lipkin inversor), invented in 1864, was the first true planar straight line mechanism – the first planar linkage capable of transforming rotary motion into perfect straight-line motion, and vice versa. It is named after Charles-Nicolas … See more There is an earlier straight-line mechanism, whose history is not well known, called the Sarrus linkage. This linkage predates the Peaucellier–Lipkin linkage by 11 years and consists of a series of hinged … See more In the geometric diagram of the apparatus, six bars of fixed length can be seen: OA, OC, AB, BC, CD, DA. The length of OA is equal to the length of OC, and the lengths of AB, BC, CD, and DA are all equal forming a rhombus. Also, point O is fixed.
