What is the Center of Gravity (G) defined as?

• The point where all the vertically upward forces of support can be considered to act

• The point where all the vertically downward forces of weight of the vessel can be considered to act

• The center of volume of the immersed portion of the vessel

• The center of the vessel

What is the Center of Buoyancy (B) defined as?

• The point where all the vertically upward forces of support can be considered to act

• The center of volume of the immersed portion of the vessel

• The point where all the vertically downward forces of weight of the vessel can be considered to act

• The center of the vessel

What is the Metacenter (M) defined as?

• The point where two resultant buoyancy forces intersect

• The point where all the vertically downward forces of weight of the vessel can be considered to act

• The center of volume of the immersed portion of the vessel

• The point where all the vertically upward forces of support can be considered to act

How is the Center of Gravity (G) calculated using the moment principle?

• By summing the moments of all forces acting on the vessel

• By adding the weight of the vessel to the displacement

• By multiplying the weight of the vessel by the distance from a point

• By dividing the weight of the vessel by the displacement

What is the formula for calculating the shift of the Center of Gravity when a weight is removed?

• GG1 = (w x d) : Δ

• GG1 = (w x d) x Δ

• GG1 x Δ = w x d : Δ

• GG1 x Δ = w x d

What does the Metacenter (M) indicate about the stability of a vessel?

• It is the point where all the vertically downward forces of weight of the vessel can be considered to act

• It is the point where two resultant buoyancy forces intersect

• It is the point where all the vertically upward forces of support can be considered to act

• It is the center of volume of the immersed portion of the vessel

How is the new Center of Gravity (KG) calculated when a weight is raised vertically?

• GG1 = (w x d) x Δ

• GG1 = (w x d) - Δ

• GG1 = (w x d) : Δ

• GG1 = (w x d) + Δ

What is the Center of Gravity (G) of a body considered to be when a weight is suspended?

• At the point of suspension

• At the center of the vessel

• At the center of volume of the immersed portion of the vessel

• At the Metacenter (M)

What is the formula for calculating the shift of the Center of Gravity when a weight is moved within the body?

• GG1 x Δ = w x d : Δ

• GG1 = (w x d) x Δ

• GG1 = (w x d) : Δ

• GG1 x Δ = w x d

What is the significance of the Center of Buoyancy (B) in the stability of a vessel?

• It is the point where all the vertically upward forces of support can be considered to act

• It is the point where two resultant buoyancy forces intersect

• It is the center of volume of the immersed portion of the vessel

• It is the point where all the vertically downward forces of weight of the vessel can be considered to act
