Sentence Examples


  • If weights be suspended from various points of a hang ing chain, the intervening por tions will form arcs of equal ~ catenaries, since the horizontal tension (wa) is the same for all.
  • Again, if a chain pass over a perfectly smooth peg, the catenaries in which it hangs on the two sides, though usually of different parameters, wifi have the same directrix, since by (10) y is the same for both at the peg.
  • Hence for every tension greater than the minimum tension there are two catenaries passing through A and B.
  • Since the tension is measured by the height above the directrix these two catenaries have the same directrix.
  • Now let us consider the surfaces of revolution formed by this system of catenaries revolving about the directrix of the two catenaries of equal tension.
