II. On a machine for the solution of simultaneous linear equations

Abstract

Let B 1 , B 2 , . . . B n be n bodies each supported on a fixed axis (in is practice each is to be supported on knife-edges like the beam of a balance). Let P 11 , P 21 , P 31 , . . . . P n 1 , n pulleys each pivoted on B 1 ; P 12 , P 22 , P 32 , . . . . P n 2 , n pulleys each pivoted on B 2 ; P 13 , P 23 , P 33 , . . . . P n 3 , n pulleys each pivoted on B 3 ;
