Industrial Engineering

Industrial Engineering is the branch of engineering that deals with the creation and management of systems that integrate people and materials and energy in productive ways. An industrial engineer studies industrial productivity and makes and implements recommended changes.

What factors must be considered when changing or enhancing a design?

Who will be using the product and who is the target consumer. Will the product appeal to the consumer and how to change the design of the product that make people want to buy the product.

Where was the first steam engine used?

The first steam engine, a water pump type, was used in mines, pumping stations, and the textile industry.

What is a steam turbine jacking oil system?

at the time of turbine start up, the shaft journals are in contact with the white metal of the bearings due to the weight of the rotor. The low pressure of the lubricating oil supply when the set is stationary is insufficient to stop the metal to metal contact between journals and bearing shells. In order to prevent the metal to metal contact between journal and bearing shell during start up, which is damaging in the long term, an oil pocket machined into the bottom shell of the journal bearing is supplied with oil under high pressure. This lifts the shafting system slightly and it floats on a film oil. this is called jacking oil system of turbine

Guideways are hardened by which hardening method?

There are several ways of hardening the ways of a machine (like a lathe). Let's jump around a bit and see what's shakin' here. You are probably familiar with what is called work hardening. If you have a coat hanger you wish to cut, but have no cutters, you can bend it back and forth to change the metallic crystal structure in a specific area. Bending it makes the crystal structure smaller, and smaller crystals are harder than large ones. The flexing of the mild steel will harden it, and then it will "flex less" and finally break there. When we "work" iron (which is a material of choice for machine housings), we harden it. Shot peening, using small shot blasted on metal parts (like the connecting rods of pistons which we "upgrade" in automotive machine shops) does the same thing on the surface of the rods. It work hardens them. If we can "work" metal, we can harden it. So how do we "beat on" a lathe bed? Glad you asked. There is an industrial process that is widely used to heat, weld or otherwise modify materials called ultrasonics. Imagine a speaker, but small, very high powered and operating at a really, really high frequency (above audible sound - ultrasound). If we can "beat on" stuff with the mechanical energy created by this device, we can ultrasonically modify it. We can harden metal with it. And by ultrasonically treating the ways of a lathe bed, we can beat the heck out of the local crystal structures, reduce the size of the crystals themselves, and thereby harden the material (after which we machine it true). Ultrasonic hardening. Done deal.

How thick is 7 gauge steel?

3/16" or 0.1875"

*** 7 gauge steel sheet is .1793", not .1875" ***

Different metals have different thickness for their gauge...mild steel is .1793, aluminum is .1443, stainless steel is .1875

How do you select and establish a suitable datum?

Selecting and establishing a suitable Datum is critical, ensure your datum is at a fixed point. Normally a hole/slot. Holes and slots a normally lasor cut, ensuring they are at an extremely high tolorance already. Then reference the slot or hole to another near by slot or hole. Using these selected points will give you accruate points of measurement/datum.

Who are the five most powerful nations in the world?

Your answer is based on opinion, not facts. By facts the five most powerful nations in the world (based on economy, alliances, military, etc.)

1. America

2. Russia

3. China

4. Germany

5. France

The British were the ones closest to taking over the world, 2/3 of it. This is incorrect,America is a continent containing many large & prosperous or potentially prosperous countries,and not a Nation.You probably mean the USA,also the UK should be in 4th place,followed by France and then Germany,otherwise your list is OK.

Which is stronger iron or steel?

By strength, if you mean durability, then i'd think it was steel

iron corrodes pretty easily

What is the Short term Z bench value of a stable process?

- Z short term=6 - Z long term=4.5 in the 6sigma approach. Don't know in reality if a Z of 6 is often used in short term...

What is micro-motion study?

micromotion is the most refined technique for the analysis of an existing work center. videotapes or motion pictures and using frame-by-frame are used to uncover every possible opportunity for improvement.

How does a water tap faucet or spigot work?

Most older taps use a soft washer which, when you turn the handle of the tap, is pressed down onto a valve seat in order to stop the flow.

What is the use of rat hole equipment in drilling technology?

There is no rat hole equipment. A rat hole is a section of the well drilled to allow the entry of electric logging equipment or for use as a space to drop perforating guns inot leaving the perforated zone free of obstruction

If your are talking about the equipment to drill the rat hole for the conductor pipe, mobile auger rigs are used to drill a 24 to 30 diameter shaft 40 to perhaps 250 feet deep. A conductor pipe is then set in the drilled hole to the design depth and grouted to fill the annulus and seal the conductor pipe with the surrounding soil/rock. This process is particularly critical in gas well production and in some parts of the country require deeper conductors to improve safety and provide the necessary foundation for the oil/gas well rig and the blow-out prevention (BOP) devise that can be quiet large and heavy.

In some areas, like Western Colorado, where the desire to minimize the environmental impact of well site development is growing, some operators may install as many as 24 conductor pipes on a single location for directional drilling.

Uses of barometer?

A barometer is an instrument used to measure the atmospheric pressure. It does so by comparing the atmospheric pressure with a predefined standard pressure.

What shapes are strong in tension or strong in compression?

Shapes like triangles are strong in tension and compression due to their ability to distribute forces evenly across their three sides, preventing deformation. Arches and domes are also effective in compression, as their curved structure efficiently transfers loads downward. In contrast, long and slender shapes, like beams, are typically stronger in tension than compression, as they can withstand stretching forces better than buckling under compressive loads. Overall, the geometric configuration plays a crucial role in determining a shape's strength in tension or compression.

What is a brief and specification?

specification means to be accurate. A brief is a lesson or an explanation.

How do you read a measuring tape?

It depends upon what kind of tape it is, how the graduations are sized, what tension the tape is held at, and (for a surveyor's tape) whether the first foot or dm is forward or backward from the zero point.
