what is GM?

A ship is said to be in a condition of list when the upsetting momens are cause by internal shift of weight that can be caused due to following actions except.

A vessel's point about which her weight acts vertically downward.

is the vertical distance from the water line to the bottom of the keel; may be measured forward and aft, or amidships

Thebtime period ofnroll varies inversely as the square root of the initial metacentric height. Therefore, ships with a small GM will have.

Whatbis the ship's condition where the ships has suffered a breach of thebhull through grounding, collision or other means and water has been admitted into the hull and is free to flow in or out of the tank?

What rule which uses ordinates to calculate the water plane areas?

The actual amount of weight in tonnes that a vessel can carry 2hen losded to the maximum permissible draught ( includes fuel,fresh water, gear supplies,catch and crews)

The length of a ship's water-plane area is 70m. The lengths of the equidistantly spaced half ordinates commencing from forward sre as follows: 0,5.2,6.4,7.0,6.0,4.9,0.3. Find the area of the water plane .

For a general cargo ship in a particular loaded condition, LBP =140 m, B 19.17 m, Cb= 0.709, Cw= 0.806, draft= 8.22 m and GMt=0.45 m. Calculate the displacement of the vessel.

What is the vessel's righting energy which enables the ship to withstand any additional heeling moments.

What is the force that acts upwards through the keel (K) and is equal to the weight being borne by the blocks?

The maximum loss of Gm of concern occurs at the instant immediately prior to the ship settling on thebblocks forward and aft - this time being called as the.

Is the weight of the ship including cargo, passenger,fuel,water,stores,dunnage,and such other items necessary for use on a voyage. These bring the ships down to its ''load draft'', colloquially known as the ''waterline''

On computing areas using Simpson's Rule, lett H stands for?

What is produced from distance between the ship's center of bouyancy and the center of the lost bouyancy. The shift in the center of bouyancy produces.

What is IS CODE included fundamental principles such as general rule, against capsizing ( criteria regarding metacentric height (GM) and righting lever (GZ)); weather criterion ( severe wind and rolling criterion); effect for free surface,icing and.

What do you mean bu, Is simply a force (Wf) acting through some distance (GZ). Since displacement remains constant through all angles of heel.

This is an integration rule used to calculate the areas under a curve is called?

The ''Law of a15's'' is a rule of thumb that sets list/heel angle limits for various operating conditions. For the following situations, a ships should not list or heel past 15° which is not included on the rule.

the distance from the center of gravity of the weight to the Lcf. if the weight is shifted the distance shifted is called

The technical annex contains several additional safety measures concerning doors, freeing port , hatch way and other items. The main purpose of this measure is.

Distance of tank from midship perpendicular=146ft., LCF=24ft.,LCG=30 ft. Determine the Trimming Arm value.

Ehat happened to the bouyancy if an empty compartment is bilged?

What vessel movement is caused by the ships rolling period TR becoming resonant with the wave period. When this occurs, the ships heel ober and , in exceptional circumstances, be rolled further overbby tue action of the wave.
