What is the remedy for industrial sickness?
As industrial sickness is an umbrella term applied to various things associated with industry that make people ill and cause them to miss work. The solutions will have to be tailored to the specific industry, and only in that way can any real effect be made on improving the health and productivity of the industrial workforce. The key is an aggresive work-up on the health issues for a given segment of the industrial workforce, and usually broken down by type of work (which makes sense). Even as coal miners face overpowering respiratory threats, and foundry and mill workers have to confront major physical threats from large (heavy) quantities of extremely hot materials, each facet of industrial production has its hot-button health issues. The industrial health managers need training and experience identifying and remediating conditions that present major health threats to their respective workforces. Then they can train the rest of management and can teach the workers themselves about the best way to carry out their jobs with minimum threats to their health.

Which oil used in pneumatic lines?
une huile emulsifiante ( qui se vaporise facilement en fine gouttelette ).
What is the nominal wall thickness in a shell or head of vessels?
technically nominal wall thickness refers to pipe wall thickness (average)..if you are referring to shell/hull/fore part of a vessel, the thickness varies depending of type, size, deadweight of the vessel
What is the difference between tolerance and allowance?
Tolerance is something that is unintended measurement... whereas allowance is one that we give to the material to undergo some process in the future.... For example a cylindrical bore is done undersize to allow honing process in the future,,, and at the final operation we check whether the final size is in the given upper and lower tolerance limits... over tolerance is unintended and we process the material for average size as far as possible.
***********
Mathematically:
Tolerance = |MMC - LMC|
Allowance = MMC(interior) - MMC(exterior)
MMC - Maximum Material Condition; instance of feature dimensions that gives maximum volume, consistent with tolerances.
LMC - Least Material Condition; instance of feature dimensions that gives least volume, consistent with tolerances.
Interior - A hole is an interior feature
Exterior - A shaft is an exterior feature
It is a jig used in hand planing and cross cutting to length. You clamp it in a vise, or let the lower edge overhang the edge of a workbench. The purpose in using one is generally to avoid cutting your bench top with a saw.
What rule describes a transformation across the Y-Axis?
Since the x coordinate will change, but not the y coordinate, take (x,y) and reflect across the y axis and you have (-x,y)
What are the advantages of embossing?
It is mechanized and therefore is less time consuming than using tools, and requires less manual labour, therefore being cheaper than, for example repoussé, which uses tools to handcraft a raised pattern.
What is the machine and man ratio for garment industries?
The man to machine ratio is commonly used by organizations to calculate production output. It is a helpful way of correlating the amount of expenses and resources put into an investment versus the return. It is important to establish optimal man-machine ratio to gain high resource utilization and output
Why you are using DSP controllers in motor?
Any controller used in motors or electrical drives are only to get variable speed or variable torque or to get higher efficiency.
The controller can be anything, it might be micro controller or it can be DSP controller or may be other.
But DSP controller finds some advantages over micro controller.
Both the controllers are Digital controllers only, but DSP controller has inbuilt Analog to Digital converter, inbuilt Digital to analog converter , inbuilt counter and inbuilt pulse generator.
With a micro controller we need to assemble all the above converters, counters and pulse generators externally, so DSP based electrical drives are more popular though the cost is more compared to micro controllers.
What happens to voltage in a step-down transformer?
The voltage induced into the secondary winding will be lower than the voltage applied to the primary winding. The primary winding being the winding connected to the supply, while the secondary winding is the one connected to the load.
What is the term interchangeable means as used in machine parts?
It means that one part can be substituted for another. The two components aren't always identical, although they both serve the same purpose.
What is SPP program for Indian students?
Its Skilled Worker Program for Indian Student.
There are really bright chances to be settle in Canada for Qualified Indian Students.
20 colleges under SPP Canada all colleges are Govt. Approved colleges.
Why is the scale of a hydrometer non linear?
The volume displaced to indicate a given change in Specific Gravity; e,g., 0.001, is less in higher SG liquids. If you do the math for a typical lab hydrometer, you will find that in a liquid with a SG near 1.100, you will have about 20% less stem travel than when it is near water at 1.000. The key to remember is that the weight of the liquid displaced is equal to the total weight of the hydrometer, not just the portion of it that is submerged.
How blast furnace productivity has been improved?
1. By increasing size and improving design. 2. By injecting hydrocarbons (the C in these means less coke is needed so there's more space in the shaft for the ore) 3. Enriching the blast air with pure O2 (this increases the flame temperature where the air gets heated and it increases the production of CO.) 4. Higher pressure at the top of the blast furnace (it increases the flow rate of the gas without increasing its velocity) and 5. By changing the physical and chemical properties of the raw materials.
It depends. The 2A current, did you measure that while the soldering iron was on? Or is it rated at 2A current consumption on the device itself (on the powercable or the stem of the soldering iron). Generaly speaking you can calculted the real power consumption by using P=V*I (thus 2A*24V = 48W). But do remeber that this power consumption is in the steady state, that is, after its switch on and all transient effects have died down. To be safe allow for 3A-4A switching currents that occurs at power on.
What is the Advantages of 3 wire rtd over 2 wire rtd?
It is more accurate, a 4 wire is more accurate than 3 wire and 3 wire is more accurate than 2 wire.
How does SCADA communicate with PLC?

commnucation medium : leased lines,Ethernet,Optical fiber communication,VSAT communication.
Is a volcano a Pneumatic or hydraulic system?
Elements of both but the molten rock pyroclastic flows (Mauna Kea , Hawaii) are hydraulic, the Mt. St Helens eruption was to a large extent pneumatic as the water turned to steam.
What are the uses of IE3000 cisco?
IE3000 are industrial grade switches. The series consists of multiple modules that can be plugged into each other.
