Q3. When a two - ram hydraulic steering gear has the rudder at an angle of 30°, the hydraulic oil pressure is 60 bar and the rudder is moving at 0.033 rad/sec. The rams are 220 mm diameter and the distance between the centreline of the rams and the centre of the rudder stock is 1.1 m.

Calculate EACH of the following:

(a) the power delivered to the rudder stock;

(b) the bending moment in the tiller arm at a point 700 mm from the centre of the rudder stock.
