Wood-cement compatibility is the ratio of a parameter related to the property of a wood-cement composite to that of a neat cement paste. The compatibility is often expressed as a percentage value. To determine wood-cement compatibility, methods based on different properties are used, such as, hydration characteristics, strength, interfacial ...
The steam needs to be fed into the end of the cylinder at just the right time in the cycle to push the piston in the correct direction. In the other direction, the steam needs to be allowed to escape from the cylinder. As the crankshaft rotates, the piston rod moves up and down (or side to side in the case of a vertical cylinder) as well as in ...
These small blocks of wood can be put together easily to make a structure that, like stone, has insulation as well as thermal mass. Cordwood provides the rustic look of log cabins without the use of tons of lumber. An entire building can be constructed with just cordwood, or stones can be used to fill in the walls.

The sand that is in contact with the casting is called facing sand, and is designed for the casting on hand. This sand will be built up around the pattern to a thickness of 30 to 100 mm (1.2 to 3.9 in). The sand that fills in around the facing sand is called backing sand. This sand is simply silica sand with only a small amount of binder and no ...
Swing-piston engines were initially introduced during the 1820s as alternate steam engine designs, prior to the widespread introduction of the steam turbine.In these examples the "piston" is typically not cylindrical as in a modern internal combustion design, and is generally rectangular in cross-section as seen from the top, rotating in a flat disk "cylinder".
Cutaway side-view diagram of an axial piston pump 3-D rendering of an axial piston pump with the parts labeled Animation of an axial piston pump in operation. An axial piston pump has a number of pistons (usually an odd number) arranged in a circular array within a housing which is commonly referred to as a cylinder block, rotor or barrel.
One of the many things that make skyscrapers special is their substructure. For example, the depth of the pit that holds the substructure has to reach all the way to bedrock. If bedrock lies close to the surface, the soil on top of the bedrock is removed, and enough of the bedrock surface is removed to form a smooth platform on which to ...
A V-twin engine, also called a V2 engine, is a two-cylinder piston engine where the cylinders are arranged in a V configuration and share a common crankshaft. The V-twin is widely associated with motorcycles, primarily installed longitudinally, though also transversely. They are also used in a variety of other land, air, and marine vehicles, as ...
