Applied Naval Architecture Ch. 3 #35 A large tanker displacing 145,000 tons in SW has a GM corrected for free surface of 15.0 ft with a center tank 100 ft long and 68 ft wide containing oil (38 ft^3/LT) to a depth of 70 ft. A cross-connecting valve is opened from this tank to the adjacent STBD...

Applied Naval Architecture Ch. 3 #31 Rectangular Barge L=120 ft, B=30 ft, D=13 ft, Seawater, T= 7 ft Only weights on board are those for the inclining experiment. It is then inclined and a transverse shift of 5 tons through 20 ft heels the barge 2 degrees. After the barge is returned to upright...

Applied Naval Architecture Ch. 3 #23 A rectangular barge (L=67 m, B= 14 m, D=6 m, T=3 m, Seawater) KG=3.7 m List=6 degrees - STBD If 250 tons of cargo are to be loaded on the main deck at 7 meters above the baseline, how far to port of centerline should it be loaded so that the barge will...

Having trouble with this question: Applied Naval Architecture Ch. 3 #17 A Barge of a constant triangular cross-section is 180 ft long and has a beam of 24 ft at the waterline when floating in freshwater at 9-foot draft. A weight of 15 tons (already on board)is shifted 10 feet across the deck...

I am having trouble with this question: Applied Naval Architecture Ch. 3 #5 A shallow draft river vessel (L=310 ft, B=42 ft, T=8.0 ft, light ship conditions) Cb=0.75, Cm=0.92 Cw=0.697 The ship is drydocked to install a rubbing strip on the outer bottom. The wood strip is 220 feet long, 8 ft...
