Bilge keels are passive stability systems. On commercial shipping the bilge keel is the form of a strake, or small keel or blister, running along much of the length of the hull. They are typically fitted one on each side, low down on the side of the hull, so as not to increase the draft of the vessel.
Intensity is a measure of the strength of shaking experienced in an earthquake. The Modified Mercalli Scale represents the local effect or damage caused by an earthquake; the intensity reported at different points generally decreases away from the earthquake epicenter.
Intensity is the quality of being intense. In physics, it is the measurable amount of a property, such as force, brightness, or a magnetic field. In Earth science, the amount â¦ of damage caused by an earthquake. it can also mean the amount of energy that a wave carries past a certain area each second.ound intensity or acoustic intensity I is defin â¦ ed as the sound power Pac per unit area A. That is: I = Pac / A. The usual context is the noise measurement of sound intensity in the air at a listener's location.
