Figure 4. Stevenson dynanometer, designed by the Scotch engineer Thomas Stevenson in 1843. This instrument measured the pressure exerted by waves on a vertical surface. He used this instrument to measure the pressure of waves at the lighthouse at Skerryvore where pressures close to 30 tons per square meter were observed.
