Abstract: In this paper a flexurally supported shear plate is described. It was designed for use under oscillatory flow where the periods of motion range from 0.5 to 15 seconds. The range of possible shear measurements is ± 100 N/m2 with sensitivities as low as 0.015 N/m2. Special emphasis is placed on the calculation of corrections for secondary forces which may contribute a large proportion of the recorded apparent shear. Comparison of the corrected shear with laminar theory gives very good agreement. An example is given to illustrate the results obtained using this shear plate in an oscillating water tunnel for laminar and turbulent flow over both smooth and rough beds.
