160   ANTI-ROLL DEVICES FOR SHIPS

When the precessing gyro-axle is inclined at the angle ve to the equilibrium position, the gyroscopic torque opposing the ship's roll is

On substituting in this equation values of the precessional velocity and displacement of the gyro-axle from the equilibrium position as given in columns 5 and 7, we obtain the values of gyroscopic torque opposing the ship's roll given in column 9 of the table (p. 161). These values are plotted against time after the invention of roll, in the curve, Fig. 126.
