In electronics, a clipper is a device designed to prevent the output of a circuit from exceeding a predetermined voltage level without distorting the remaining part of the applied waveform. A clipping circuit consists of linear elements like resistors and
An operational amplifier (often op-amp or opamp) is a DC-coupled high-gain electronic voltage amplifier with a differential input and, usually, a single-ended output. In this configuration, an op-amp produces an output potential (relative to circuit ground) that is typically hundreds of
When a ship heels, the centre of buoyancy of the ship moves laterally. It might also move up or down with respect to the water line. The point at which a vertical line through the heeled centre of buoyancy crosses
Prime numbers are natural numbers greater than 1 that has no positive divisors other than 1 and itself. A number that is not a prime is called composite, except 1 because 1 is considered neither a composite nor prime. For instance, 7 is
In its simplest form, concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the
Concrete is a mixture of paste and aggregates, or rocks. The paste, composed of portland cement and water, coats the surface of the fine (small) and coarse (larger) aggregates. Through a chemical reaction called hydration, the paste hardens and gains
The importance of concrete in modern society cannot be overestimated. Look around you and you will find concrete structures everywhere such as buildings, roads, bridges, and dams. There is no escaping the impact concrete makes on your everyday life. So
Coarse aggregates are particles greater than 4.75mm, but generally range between 9.5mm to 37.5mm in diameter. They can either be from Primary, Secondary or Recycled sources. Primary, or ‘virgin’, aggregates are either Land- or Marine-Won. Gravel is a coarse marine-won
Aggregate is a granular material obtained by processing natural materials. BS882 splits aggregate into coarse and fine elements, coarse being described as gravel or crushed rock and fine being described as sand.Aggregate consists of particles of a rock, of a
Concrete is an ancient material of construction, first used during the Roman Empire. Concrete today is a sophisticated material to which exotic (foreign) constituents can be added and, with computer-controlled batching, can produce a product capable of achieving 50,000 psi compressive strength.
