What is the meaning of Metacentric?

What is the meaning of Metacentric?

Definition of metacentric 1 : of or relating to a metacenter. 2 : having the centromere medially situated so that the two chromosomal arms are of roughly equal length.

What is metacentre of a ship?

The metacentre is the point where the lines intersect (at angle φ) of the upward force of buoyancy of φ ± dφ. When the ship is vertical, the metacentre lies above the centre of gravity and so moves in the opposite direction of heel as the ship rolls. This distance is also abbreviated as GM.

What is metacentre and metacentric height?

Hydraulics and Fluid Mechanics. The Metacentre may be defined as a point about which a floating body starts oscillating, when given a small angular displacement. It is denoted by M. The metacentric height is the distance between the centre of gravity (G) of the floating body and the metacentre (M).

How do you calculate metacentre?

Calculation of Metacentric height

1. When, M1 = M2.
2. ϒ I tan θ = ϒ V .
3. Therefore BM = I /V and MG= BM – BG, if G is above B and.
4. If G is below B, Metacentric height MG = BM + BG.

What is Metacentric Submetacentric and Acrocentric?

Metacentric chromosomes have a centromere in the middle of the chromosome, telocentric chromosomes have a chromomere at the end and acrocentric chromosomes have a chromomere near the end of the chromosomes. Chromosomes are present in the nucleus and they carry genetic information.

What is the difference between Metacentric and Submetacentric chromosome?

Metacentric chromosomes have the centromere located midway between the ends of the chromosome, separating the two arms of the chromosome (Figure 1). Chromosomes with centromeres positioned visibly off-center are called submetacentric.

What is the use of metacentre?

If the metacentre is above the centre of gravity, buoyancy restores stability when the ship tilts. The stability increases with the distance between metacentre and centre of gravity, called the metacentric height. If the metacentre is below the centre of gravity, the boat is unstable, and a tilt results in capsizing.

What is centre of buoyancy and metacentre?

Centre of buoyancy is defined as the point at which the centre of gravity of the displaced liquid lie. Metacentre is the point of intersection of the vertical line passing through C.B. and original vertical line.

What do you mean by metacentric height?

Definition of metacentric height : the distance of the metacenter above the center of gravity of a floating body.

What is KB in ship stability?

The vertical distance (along the ship’s centerline) between the keel and the centre of buoyancy is expressed as ‘KB’, as shown in Figure 3.

What is Telocentric and Metacentric?

What is difference between Metacentric and Submetacentric?

What is meant by Submetacentric?

Definition of submetacentric : having the centromere situated so that one chromosome arm is somewhat shorter than the other.

What is angle of loll in ship?

Angle of loll is the state of a ship that is unstable when upright (i.e. has a negative metacentric height) and therefore takes on an angle of heel to either port or starboard.

What is the difference between centre of gravity and centre of buoyancy?

Center of Gravity is the point in a body where the gravitational force may be taken to act. Center of Buoyancy is the center of the gravity of the volume of water which a body displaces.

What is GZ in stability?

Definitions. 19. STABILITY CURVES (GZ CURVES) Stability curves (GZ curves) are used to show graphically the stability levers (GZ) exerted by a vessel to return itself to a position of equilibrium from the various conditions of heel.

What is km stability?

KM – Height of Metacenter above the Keel: This measurement is found by using the Draft Diagram and Functions of Form Curves located in section II(a) of the DC Book. GM – Metacentric Height: This measurement is calculated by subtracting KG from KM (GM = KM – KG). GM is a measure of the ship’s initial stability.
