How is 4140 steel welded to AR400 steel?
Best Way, I have found is a low hydrogen electrode or wire, preheat to 3-400C make sure to bevel so weld only is attaching to one material per pass, small stringers, keep the heat as welding, post heat back to 3-400C, let cool by propane space heater. (Excavator buckets etc..? Yeah- we can do that at Rods M Shop.
What are safety practices using inside caliper?
You can calculate pressure and temperature for a constant volume process using the combined gas law.
about 5 seconds.
280*7(7 gals per cu foot)=1960 gals/min.
1960/60(sec. per min.)=32.6 gals/sec.
160(tank size)/32.6=4.9 sec.
this is all theoretical. the supply line to feed such a pump would have to be huge!
A vector whose direction (angles) and line of application are fixed, but whose point of application is not fixed.
Is a hairdryer a pneumatic system?
A hair dryer is actually not a good example of a pneumatic system. A pneumatic or hydrologic system uses fluid (gas or liquid) to transfer force over a distance. Hair dryers lack almost all components found in a pneumatic system. The internal operation of a hair drier is simple, a fan creates a high pressure air pocket on the heating element, and this high pressure air pocket cause air to be sucked in the back, and pushed out the blowing end.
Hopefully this helps your endeavors. J. Salsieder

Is bbm better or engineering better?
BBM is better now than Engineering.lots of engg colleges are existing now a days and there is recession going on now,then getting into gud companies are gettin tougher 2 engg students.Better 2 do BBM or BBA now a days 2 still hav high hopes on career.If u r career oriented then better 2 do BBM or if u want some gud subjects 2 be learned then engg is better 4 u.
Why balancing is require in steam engines?
If you think of a steam engine as a machine either any machine is balanced or it will tear itself apart in normally use
What lens shade for 024 wire mig welding?
Depends on multiple factors, amperage, the person and their eyesight, toleration to light. I would suggest you start at shade 10 and work downwards with shade 7 being as low as you go.
What is easier to weld carbon steel or cast iron?
any steel or alloy of iron and carbon having a carbon percentage of above 0.3% is difficult to weld. carbon steel can have maximum carbon percentage of about 2% and cast iron with carbon percentage between 2% to 4%. the welding of any iron alloy with carbon percentage above 0.3% becomes difficult because of the formation of the martensite in the welding areas, heat affected zone etc., the fusion welding process which is usually employed to weld carbon steel and cast iron takes the metal or alloy to their respective melting point (in this case about 1650 C) which is above the austenizing temperature of most steel and cast iron. when the weld is finished it undergoes a process similar to hardening. the nearby non heated parts of the welded material acts as the cold bath resulting in the hardening process which involves sudden cooling for the formation of martensite which is very brittle, any pressure applied will crack the weld immediately. hence before welding the nearby parts of the material to be welded is preheated so that they wont act as any cold bath. but any way cast irons are very difficult to weld than the steels. this is because of the fact that the martensite formed is as a result of trapped carbon atoms in the iron crystal making a distorted body centered tetragonal crystal structure(martensite). higher the percentage of carbon the martensite formation is even better. hence cast irons are especially difficult to weld. design engineers never suggest a welding process for cast iron. cast irons are welded only when there is no other choice but to weld it.
What is mist lubrication system?
Mist lubrication system is that, in which the lubrication of a bearing is done by the oil in the form of oil mist.
How is the cooling mechanism implemented in fanless laptops?
The most common way that I have seen in my professional experience is by slowing down the operational speed of the processor inside the machine. The idea behind having no fans in the computer is to cut noise down to only that produced by the clacking of the keyboard and the clicking of the mouse buttons. For the modern computer and its performance, I would rather have the very slight noise of a fan (most are quieter than a cat's snore--and I should know since I have three cats, five desktops, and two laptops) than to have the significant performance hit.
For those who want to be trendy, go ahead and pay the upcharge for a less-capable but only slightly-quieter machine. One warning, though: be aware that there is a greater potential for damage to the machine if there is no fan. In the case of the CPU overheating, the machine may not be as capable of dissipating the heat as it would in a fan-cooled configuration. The reason being that a fanless machine also has no heatsink of any significant size (if any at all) to draw the heat away, so that means that even if the CPU's thermistor does turn off the system due to the overheat condition (and that is not guaranteed since the CPU has been slowed down and installed in a configuration for which it was not designed), the CPU will still be at its excessive temperature and not have anything to which to drain the excess heat other than the motherboard and nearby components. At least with a fan-cooled system, the CPU still has a decent heatsink that can be used to take soak up most of the heat, thereby protecting the motherboard and other surface components in close proximity to the CPU even if the fan has failed.
Where can I get a Mechanical Engineering degree online?
Many colleges and universities offer online degree plans, but Ferris is one of the more popular options for this particular need. Check with your local college/university for more options.

What is the transmission angle?
Angle between coupler link and output link for a given crank angle is called transmission angle, it is maximum when crank angle is 180 degree and minimum when crank angle is 0 degree
Whats the role of finance department in a company?
The role of the finance department in a company depends a lot on the size of the company. At the very least, the finance department will take care of the day to day transactions of the company through basic bookkeeping. In larger companies, the finance department may assist department managers in making strategic decisions and prepare forecasts for calculating ongoing cash needs.
