Circular slide rule by Troughton and Simms, designed by William Froude c.1877, with inscription plate and three logarithmic scales, used at the Admiralty Experimental Establishment, by Troughton and Simms, London, 1887
This circular slide rule was designed and used by the ship-design expert William Froude. It
was manufactured by the prominent mathematical-instrument makers, Troughton &
Simms, and speeded up calculations.
Froude spent the 1870s carrying out a series of experiments on ship design using the
world’s first ship test tank, built by the Admiralty near his house in Torquay. He used the
slide rule in his work relating experimental results to mathematical theory.
