Quick Answer: What Are The Conditions Of Equilibrium Of A Floating Body?

What are the conditions for stable equilibrium?


… equilibrium is said to be stable if small, externally induced displacements from that state produce forces that tend to oppose the displacement and return the body or particle to the equilibrium state.

Examples include a weight suspended by a spring or a brick lying on a level surface..

Which principle is used for calculating the Centre of pressure?

3. Which principle is used for calculating the centre of pressure? Explanation: We balance the moment in order to calculate the position of centre of pressure. Explanation: Pressure at every point is different as the depth of different point from is different.

What would happen if the metacentric height is negative?

If GM is negative, the ship will capsize when inclined. The ship’s roll period is directly related to the Metacentric Height of your vessel.

What buoyancy means?

1a : the tendency of a body to float or to rise when submerged in a fluid testing an object’s buoyancy. b chemistry : the power of a fluid to exert an upward force on a body placed in it the buoyancy of water also : the upward force exerted.

What are the three conditions of equilibrium?

A solid body submitted to three forces whose lines of action are not parallel is in equilibrium if the three following conditions apply :The lines of action are coplanar (in the same plane)The lines of action are convergent (they cross at the same point)The vector sum of these forces is equal to the zero vector.

What are the conditions of equilibrium of a floating body and a submerged body?

Conditions Of Equilibrium Of Floating AndSubmerged Bodies. A floating or submerged body is said to be stable if it comes back to its original position after giving a slight disturbance. The condition of stability of these bodies depends on the position of its metacentre, centre of buoyancy and centre of gravity.

What is meta centric?

Metacentre. When a ship heels (rolls sideways), the centre of buoyancy of the ship moves laterally. It might also move up or down with respect to the water line. The point at which a vertical line through the heeled centre of buoyancy crosses the line through the original, vertical centre of buoyancy is the metacentre.

What are the conditions of equilibrium of a submerged body?

The equilibrium of a body submerged in a liquid requires that the weight of the body acting through its cetre of gravity should be colinear with an equal hydrostatic lift acting through the centre of buoyancy.

Which statement is correct for stable equilibrium for floating body?

A floating body is said to be in stable equilibrium if its metacentre lies above the center of gravity.

How they influence the stability of a floating body?

A floating body is STABLE if, when it is displaced, it returns to equilibrium. A floating body is UNSTABLE if, when it is displaced, it moves to a new equilibrium. … For the untilted body the point G is the centre of gravity of the body where the body weight, W, acts.

How do you know if an equilibrium is stable?

An equilibrium is considered stable (for simplicity we will consider asymptotic stability only) if the system always returns to it after small disturbances. If the system moves away from the equilibrium after small disturbances, then the equilibrium is unstable.

What is Metacentre of a floating body?

Metacentre, also spelled metacenter, in fluid mechanics, the theoretical point at which an imaginary vertical line passing through the centre of buoyancy and centre of gravity intersects the imaginary vertical line through a new centre of buoyancy created when the body is displaced, or tipped, in the water, however …

What types of equilibrium are there?

There are three types of equilibrium: stable, unstable, and neutral. Figures throughout this module illustrate various examples.

What are the two main conditions for equilibrium?

Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium).
