s the centreline of the vessel, CB is the rudder whenat an angle of 42 degs. CA is the samerudder at 90 degs.. From B draw BDparallel to XY. Then CD = CB x sine42 degs. Again set off Bd to representthe force against a unit area when at rightangles to the current. Resolve this forceinto Bb and bd,… … Fig. 70. igS HYDRAULICS. quantity of water arrested being less, and again by sine 42 degs.to correct it, for the action upon the rudder being oblique. (Sine42 degs. = 669). Effective force = 40824 x -669 x -669,, = 18271 lbs. The problem is now purely a shaft problem; for the leverage with which…
