## What causes hogging and sagging?

Hogging is the stress a ship’s hull or keel experiences that causes the center or the keel to bend upward. Sagging is the stress a ship’s hull or keel is placed under when a wave is the same length as the ship and the ship is in the trough of two waves.

What are the stresses on the ship and explain?

The static forces are due to the difference in the weight and buoyancy, which occur through out the ship. The dynamic forces are cause by the motion of the ship at sea and the action of the wind and wave. These forces create: Longitudinal stress.

Is hogging positive or negative?

## Why do ships bend hog and twist at sea?

Any massive seafaring ship worth its weight in salt is designed to flex through rough watersâ€”the maritime engineers and architects who build these things pore over a range of calculations to allow big ships to twist slowly side to side like a sea snake on Ativan, and also bow up and down (this is what’s known as hog …

Panting stringers are longitudinal stiffening members formed in a closed rounded-triangular shape (peak being the fore end) by the side stringers on both sides and the collision bulkhead at its end. A perforated bulkhead often exists at the centreline.

### What is meant by sagging moment?

a bending moment that produces concave bending at the middle of a simple supported beamAlso called: positive bending moment.

What is pounding of ship?

Pounding: When a ship sails in heavy seas, it pitches. It can happen that the bow rises over the crest of a wave and emerges completely out of the water. When the bow comes back down on the water, it can be subjected to a major impact, which is pounding.

How to prevent hogging and sagging of boat?

Preventing hogging and sagging can be done by having the following structural members; Keel, floor timber and hog piece. The keel is the primary fore and after member of a boat, constituting the backbone of the structure and aiding in the prevention of hogging and sagging.

## What is the difference between sagging and hogging bending moment?

A Sagging Bending Moment is the bending moment that causes a beam to bend with the concave side upwards. This bending moment is referred to as a positive bending moment. A Hogging Bending Moment, on the other hand, is the bending moment that causes a beam to bend with the concave side downwards.
