One complete cycle of a four-cylinder, four-stroke engine.The volume displaced is marked in orange. Engine displacement is the measure of the cylinder volume swept by all of the pistons of a piston engine, excluding the combustion chambers. [1]
Consider the linear subspace of the n-dimensional Euclidean space R n that is spanned by a collection of linearly independent vectors , …,. To find the volume element of the subspace, it is useful to know the fact from linear algebra that the volume of the parallelepiped spanned by the is the square root of the determinant of the Gramian matrix of the : (), = ….
Animation of the 1-2-4-5-3 firing order MAN B&W 5S50MC 1,865 litre marine diesel engine. Straight-five engines are typically shorter than straight-six engines, making them easier to fit transversely in an engine bay. [1]
A woman described her battle with pain for the better part of 20 years — until an MRI scan finally revealed what was causing her so much discomfort. Here's what she learned about endometriosis.
On 7 April 1795, the metric system was formally defined in French law using six units. Three of these are related to volume: the stère (1 m 3) for volume of firewood; the litre (1 dm 3) for volumes of liquid; and the gramme, for mass—defined as the mass of one cubic centimetre of water at the temperature of melting ice.

The van der Waals radius, r w, of an atom is the radius of an imaginary hard sphere representing the distance of closest approach for another atom. It is named after Johannes Diderik van der Waals, winner of the 1910 Nobel Prize in Physics, as he was the first to recognise that atoms were not simply points and to demonstrate the physical consequences of their size through the van der Waals ...
TLC: Total lung capacity: the volume in the lungs at maximal inflation, the sum of VC and RV. TV: Tidal volume: that volume of air moved into or out of the lungs in 1 breath (TV indicates a subdivision of the lung; when tidal volume is precisely measured, as in gas exchange calculation, the symbol TV or V T is used.)
McKendree cylinders are a type of habitat in the fictional universe of the Orion's Arm world-building project, but scaled up to the theoretical limits of carbon nanotubes: 1,000 km in radius and 10,000 km long, containing 63 million km 2 (24 million sq mi) of living space—greater than the continent of Eurasia.
