1A vessel floating in seawater has a height of center of buoyancy KB = 3.50 m, transverse metacentric radius BM = 4.20 m, and center of gravity KG = 6.80 m. What is the initial transverse metacentric height (GM)?
A.0.90 m
B.1.10 m
C.2.60 m
D.14.50 m
Explanation: The transverse metacentric height is calculated as GM = KM - KG, where KM = KB + BM. Here, KM = 3.50 m + 4.20 m = 7.70 m. Therefore, GM = 7.70 m - 6.80 m = 0.90 m.
2Which of the following fundamental equations defines the transverse metacentric radius (BM) of a ship floating at displacement volume V?
A.BM = I / V, where I is the transverse second moment of area of the waterplane
B.BM = V / I, where I is the longitudinal second moment of area of the waterplane
C.BM = I * V, where I is the total wetted surface area
D.BM = KB + KG
Explanation: By definition, the metacentric radius BM equals the transverse second moment of area of the waterplane (I) divided by the underwater displacement volume (V), i.e., BM = I / V.
3A ship waterplane has transverse second moment of inertia I = 15,000 m^4 and displacement volume V = 5,000 m^3. What is the value of BM?
A.3.00 m
B.0.33 m
C.75,000 m
D.10.00 m
Explanation: BM = I / V = 15,000 m^4 / 5,000 m^3 = 3.00 m.
4What is the effect on a vessel's center of gravity (KG) when a heavy weight is shifted vertically upwards within the vessel?
A.KG increases (moves upwards), reducing metacentric height GM
B.KG decreases (moves downwards), increasing metacentric height GM
C.KG remains unchanged because no weight was added or removed
D.BM increases proportionally to offset the shift
Explanation: Shifting a weight upwards raises the overall center of gravity (increases KG). Since GM = KM - KG, an increase in KG directly reduces GM and impairs initial transverse stability.
5During an inclining experiment on a 3,000-tonne vessel, moving a mass w = 15 tonnes across the deck by a distance d = 10 m produces a heel angle theta where tan(theta) = 0.05. What is the fluid metacentric height (GM)?
A.1.00 m
B.0.50 m
C.2.00 m
D.1.50 m
Explanation: The inclining experiment formula is GM = (w * d) / (Delta * tan(theta)). Substituting values: GM = (15 tonnes * 10 m) / (3,000 tonnes * 0.05) = 150 / 150 = 1.00 m.
6According to Simpson's First Rule (1/3 Rule), what are the standard multipliers for five equally spaced ordinates (y0, y1, y2, y3, y4)?
A.1, 4, 2, 4, 1
B.1, 3, 3, 1, 1
C.1, 2, 2, 2, 1
D.1, 1, 1, 1, 1
Explanation: Simpson's First Rule (1/3 Rule) uses Simpson's multipliers [1, 4, 2, 4, 1] for five ordinates bounding four equal intervals h.
7Using Simpson's 1/3 Rule with ordinate spacing h = 3 m, half-ordinates are y0 = 0, y1 = 4, y2 = 5, y3 = 4, y4 = 0 m. What is the total waterplane area for both sides?
A.72 m^2
B.36 m^2
C.108 m^2
D.54 m^2
Explanation: Applying Simpson's First Rule multipliers [1, 4, 2, 4, 1] for ordinate offsets y = [0, 3, 6, 3, 0] spaced at interval h = 3 m: Sum = 1(0) + 4(3) + 2(6) + 4(3) + 1(0) = 0 + 12 + 12 + 12 + 0 = 36. Half-waterplane area = (h / 3) × Sum = (3 / 3) × 36 = 36 m². Total symmetric waterplane area = 2 × 36 = 72 m².
8What is the virtual loss of metacentric height (GG1) caused by a slack liquid fuel tank of length L = 20 m, breadth b = 6 m, containing oil of density rho_f = 0.85 t/m^3 on a vessel of displacement Delta = 4,000 tonnes floating in seawater (rho_s = 1.025 t/m^3)?
A.0.075 m
B.0.360 m
C.0.150 m
D.0.018 m
Explanation: Transverse moment of inertia of rectangular tank waterplane i = L * b^3 / 12 = 20 * 6^3 / 12 = 20 * 216 / 12 = 360 m^4. Free surface reduction GG1 = (i * rho_f) / (Delta * rho_s) = (360 * 0.85) / (4,000 * 1.025) = 306 / 4,100 = 0.0746 m (approx 0.075 m).
9When a ship experiences a small angle of heel theta (less than 10-15 degrees), the righting arm GZ is approximated by which linear relationship?
A.GZ = GM * sin(theta)
B.GZ = BM * cos(theta)
C.GZ = KB * tan(theta)
D.GZ = KG * sin(theta)
Explanation: For small heel angles where the metacenter M remains virtually fixed, righting arm GZ = GM * sin(theta).
10In ship hydrostatics, what is the 'margin line' defined under SOLAS passenger vessel damage stability rules?
A.A line drawn at least 76 mm below the upper surface of the bulkhead deck at side
B.The line of maximum summer load draft painted on the midship hull
C.The line joining the centers of gravity of all wing ballast tanks
D.The waterline corresponding to maximum lightship displacement
Explanation: Under SOLAS damage stability regulations, the margin line is a line drawn continuously at least 76 mm (3 inches) below the upper surface of the bulkhead deck at the side of the ship, which must not be submerged after flooding.
