Scientific instruments may be usefully regarded as the capital goods of the research industry. That is to say, the conduct of scientific research generally requires some antecedent investment in specific equipment for purposes of enhancing the ability to observe and measure specific categories of natural phenomena. Moreover, much of the scientific instrumentation that is now in existence had its historical origins in the conduct of basic research - specifically, in the attempt to advance the frontier of scientific knowledge through an expansion in observational or experimental capabilities. In this sense, a central part of the "output" of the university research enterprise has been much more than just new theories explaining some aspects of the structure of the universe, or additional data confirming or modifying existing theories. A further output (or by-product) has been more powerful and versatile techniques of instrumentation including, in many cases, the ability to observe or measure phenomena that were previously not observable or measurable at all. New instrumentation has thus often been an unintentional and, to a surprising extent, even an unacknowledged, product of university research.

A common denominator among a wide range of scientific instruments is that they were initially designed in response to some very specific, narrowly defined requirement of research in a particular discipline. However, after their successful development, it became apparent that the instrument had useful applications in some other scientific realm - whether basic or applied - often requiring substantial modification or redesign. The analogy with more conventional capital goods should be apparent here. Machine tools originally designed to meet the specific requirements of textile or locomotive or musket manufacturers were later transferred to manufacturers of sewing machines, bicycles, typewriters, and automobiles. Such transfers have been numerous and diverse. [2] Similarly, scientific instruments designed to improve technical capability or to solve one set of research problems have often turned out to have applications in disciplines and technology sectors far from those where they originated. The most spectacular of such transfers has involved the computer. Computers are, of course, the scientific instrument par excellence; their origins can be traced to research conducted in several countries, although the research context from which they originally sprang is now largely forgotten. In the past thirty years, computers have become indispensable wherever extensive calculations are made - which is to say everywhere in the scientific world. The demand for greater calculating capability turned out to be enormous when the cost of computing was reduced by many orders of magnitude. The computer has made possible many kinds of research activities that would have been simply impossible if computational costs and capabilities had remained frozen at the levels which prevailed at the outbreak of the Second World War. Moreover, much of the progress in research capability in the past couple of decades has occurred by linking other new scientific instruments to the computer. This includes computer control of a wide range of experiments that could hardly have been undertaken in its absence. In addition, the availability of powerful computers has opened up the possibility of large-scale simulation of physical and biological processes.

At the same time, the computer has spread into uses in business, government, medical care, and private households which are extremely remote from its scientific points of origin, and certainly very far from the specific purposes that dominated the thinking of the pioneers of computing. A quick stroll, for example, through the intensive care unit of any major hospital will disclose a number of essential technologies that are directly dependent upon the computer for the continuous monitoring of vital signs: blood pressure, respiratory rate, pulse rate, and cardiac rhythm.

A common denominator among many of the pioneers in developing the computer - Howard Aiken at Harvard, John Atanasoff at Iowa State University, Konrad Zuse in the German aircraft industry, and John P. Eckert, Jr. and John W. Mauchly at the University of Pennsylvania - is that their contributions resulted from the fact that they were confronted by extremely tedious and time-consuming computational requirements in their research work, typically involving solutions to large systems of differential equations. [3] Interest in useful applications of this capability outside the sphere of research (including military R&D during the Second World War) was, for a long time, limited or non-existent. [4]

This question is incorrect; engineering is as suitable for women as it is for men. While most engineering workplaces are male dominated, that doesn't mean that women can't do the work just as well. However, women wishing to go into engineering should be prepared to deal with the stereotypical view that engineers are men.

INDUCTION

At normal room temperatures, mercury has a low vapor pressure combined with a high mass, which makes diffusion pumping more efficient.

ABS plastic, which stands for Acrylonitrile Butadiene Styrene, is a type of thermoplastic polymer made from a combination of three main monomers: acrylonitrile, butadiene, and styrene. These monomers are chemically bonded together through a polymerization process to create the final ABS plastic material.

Here's a breakdown of the components and their roles in ABS plastic:

Acrylonitrile: This monomer provides chemical resistance and heat stability to ABS. It contributes to the material's rigidity and strength.

Butadiene: Butadiene adds impact resistance and toughness to ABS. It helps the plastic absorb and dissipate energy, making ABS less brittle and more durable.

Styrene: Styrene enhances the surface finish, processability, and ease of coloring of ABS plastic. It also contributes to the material's rigidity.

The combination of these three monomers results in a versatile and well-balanced plastic material that offers a blend of strength, impact resistance, heat resistance, and surface finish. ABS plastic is widely used in various industries for applications such as automotive parts, consumer goods, electronics, toys, medical devices, and more. Its properties can be further modified by adjusting the ratios of these monomers and by incorporating additives or fillers during the manufacturing process.

ABS plastic sheets are flat, rigid panels made from ABS (Acrylonitrile Butadiene Styrene) polymer. These sheets are widely used in various industries for a range of applications due to the favorable properties of ABS, such as its durability, impact resistance, and versatility. ABS plastic sheets come in different sizes, thicknesses, colors, and finishes to suit specific project requirements.

Applications of ABS Plastic Sheets

Automotive Industry: ABS sheets are used to create interior and exterior automotive parts, including dashboard panels, trim components, and interior liners, thanks to their ability to withstand impact and provide a smooth finish.

Electronics and Appliances: ABS plastic sheets are used for housings, covers, and structural components of electronic devices and appliances due to their electrical insulation properties and ability to be easily molded and machined.

Consumer Goods: ABS sheets are employed to manufacture a wide range of consumer goods, such as luggage, toys, cosmetic cases, and kitchen appliances, due to their aesthetics, durability, and ease of processing.

Signage and Displays: ABS sheets are popular for creating signs, displays, and point-of-sale materials due to their ability to be easily formed into different shapes, painted, and printed on.

Construction and Architecture: ABS sheets find applications in architectural models, wall cladding, and decorative elements due to their ease of fabrication and availability in various textures and colors.

Medical Devices: ABS plastic sheets are used to make medical equipment components, as they are durable, easy to sterilize, and resistant to chemicals commonly used in medical environments.

DIY and Craft Projects: ABS sheets are utilized by hobbyists, DIY enthusiasts, and crafters to create custom parts, prototypes, and artistic projects due to their ease of handling and finishing.

Educational Materials: ABS sheets are used in educational settings for creating prototypes, models, and visual aids due to their versatility and ease of manipulation.

Key Properties of ABS Plastic Sheets:

Impact Resistance: ABS plastic sheets have good impact resistance, making them suitable for applications where durability is essential.

Ease of Fabrication: ABS sheets can be easily cut, drilled, machined, and thermoformed, allowing for various fabrication techniques.

Surface Finish: ABS sheets can be manufactured with a smooth, glossy surface or textured to mimic different materials like wood or leather.

Chemical Resistance: ABS plastic sheets have reasonable resistance to a wide range of chemicals, making them suitable for various environments.

Color and Appearance: ABS sheets can be easily colored, painted, or printed on, allowing for customizable aesthetics.

Temperature Resistance: While ABS has moderate heat resistance, it can soften or deform under high temperatures, so it's important to consider the specific temperature requirements of your application.

When selecting ABS plastic sheets, consider the factors mentioned in the previous response, such as quality, customization options, manufacturer reputation, and suitability for your project's needs.

If the fire is hot enough, and there is enough oxygen, the steel will burn. (think cutting torch) The simplest answer is that the steel heats up. A cutting torch doesn't "burn" the metal away... it melts the metal along your cutting line. Very few chemicals can oxidize steel with enough ferocity to burn it with a flame. A couple of exceptions that I have seen in my career were F2 and ClF3. Of course those are very strong oxidizers. Heating steel to a prescribed temperature then either quenching it quickly or holding the temperature a a certain level for a period of time will alter the grain structure and therefore the properties of the steel. Think tempering. You can learn much more about that by researching steel phase diagrams. Time-temperature relationships are the oldest and most common methods of changing a metals strength and hardness.

As low as 126 degrees Fahrenheit, diesel fuel could potentially catch on fire. This is known as the temperature of ignition.

Lets liken this to a garden hose, a hose in the normally open position has water flowing through it until it is closed by turning the spigot off, normally closed is the reverse. Oddly enough when it comes to an electronic relay the opposite is true, whereas the switch is in the open (normally open) position therefore having no current passing through it until a switch to close the circuit and allow current to flow. Normally closed has current flowing at all times until the switch interrupts it stopping the flow of electricity.

Fretting corrosion is a complex process which involve chemical corrosion and friction (by asperities, surface irregularities) between components in motion, fluids moving in tubes, etc.

Muriatic Acid is good at dissolving cement, as well as RoMix Back Set Molecular Cement Dissolver

A positive displacement pump ( gear, vane or piston pump) is driven by a prime mover (Electrical Motor or Engine) it sucs fluid from reservior and delivers oil to system. During loading a resistance to flow creates the pressure which is utilised to do the work through cylinder for linear motion or through hydraulic motor for rotary motion, Direction of flow is changed with help of direction control valve & system pressure is regulated by pressure control valve & flow is regulated by flow control valve

galvanized metal is a silvery gray colour which also has a pattern on it.

These two laws they are similar.

But Hooke's Law is a law which is used in Solid Mechanics, and Newton's Law of Viscosity is the one which is used in Fluid Dynamics.

Fused silica has 2 meanings: previously fused silica and presently fused silica.

Previously fused silica is fused by heating it to its melting point. This can be done in crucible in a furnace.

Presently fused silica is already hot and fused.

Note: melted silica is probably a conductor, at least melted glass is a conductor.

A gas will always have a lower density than its corresponding solid or liquid, and thus could not sink in its own liquid.

Gasses can, of course, be absorbed/dissolved into liquids.

One of the least dense liquids would be liquid hydrogen with a density of about 67.8 kg/m3

One of the densest gasses (at 1 ATM) is Radon Gas at about 9.73 kg/m3. Thus, it would still float in liquid hydrogen at 1 ATM.

However, the density of gasses is a function of the pressure and temperature, so at extreme pressures, Radon gas would likely sink in liquid hydrogen.

The density of the atmosphere at the surface of Venus is about 67 kg/m3, and thus it might sink in liquid hydrogen (ignoring, of course, the temperature and pressure differences).

An average electronic engineer makes about $85, 350 per year. This amount can go above $125,000 or fall down below $52,000 per year. Electronic engineer's work is to create, test and oversee various electronic devices.
