Each propeller of the twin-screw ship develops a full-speed thrust of F = 210 kN. In maneuvering the ship, one propeller is turning full speed ahead and the other full speed in reverse. What thrust P must each tug exert on the ship to counteract the effect of the ship's propellers? -60 m- 12 m 100 m Answer: P = kN the tolerance is +/-2%
