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.
What is the definition of intensity in terms of sound? Sound intensity or acoustic intensity (I) is defined as the sound power (Pac) per unit area (A). The usual context is the noise measurement of sound intensity in the air at a â¦listener's location as a sound energy quantity (measured in W/mÂ²).
