Im trying to think of the name for that wheel on the end of a stick that you walk with, and it clicks every metre or so, to measure distance. What's it called?

When you create something, what are you doing really? It seems to me like it's simple arithmetic. For example, imagine your average modern bicycle. No one can imagine that design out of nowhere. Even if they're genius, they have to see it part by part. To understand something, you have to break each part down into single concepts. Hence the term "part." You then take into account the effect of putting parts together, (i.e., part 1 + part 2 = operation 1 in your mind.) Those two parts and their operation might become a new single concept in your mind--a new part, allowing you to go further with your creation. The parts of a bicycle that you buy from a store have their own parts as well. Them and their operations had to be worked through minds, combined, tested, and reconfigured until, finally, we get the bicycle. So, what do you think? Can we ever really invent or do we just collect, analyze, reassemble, and combine?

The temperature in production tank is mantain at 40*C, the water capacity to cool down is 200L. I have measure the water flow is 1L- 8 seconds, so 200L is 1600 sec. or 26 min, 22,050Btu/hr My compressor is 62,000Btu/hr or15,600Kcal/hr cooling capacity. I want the temperature become 26*C in production tank.

Hi. I need to know the exact steps and amnufacturing processes used to create an angle valve for water supply. This is the valve for toilets, some sinks, etc. There is more than one piece to the valve. I need the process from raw material to machining. I also would like to know the typical steel used and an accurately estimated yearly production if available. Thanks for your input. :)

I'm a junior now in high school and wish to pursue a career in Chemical or Nuclear engineering. I do well in all subjects and take all the possible Honors/AP Courses at my school , and I have received all A's. I was wondering if Chemical Engineering is a good choice as a major. I like Chemistry and Math and have a good work ethic. Please tell me of your experience as a student or as an engineer ( study habits, like your job, pay, etc. ) Thanks

We used Bell wire, could this be the problem? We have a zinc screw on one part, a copper penny on the other part with bell wire and aligator clips going from them to the light, what else!?

I.e. like how those electromagnets in scrap yards pick up junk, i was wondering if there is any kind of relationship that governs the strength of the magnet and how far away it can be from the object its attracting so that it will jump up to attach itself to the magnet. any suggestions?

It is going to be used as a planting table for wheel chair students in a greenhouse. It will be about 36" wide, 72" long, and adjustable from 29" to 36" high. I need ideas on how to make it adjust safely, easily and inexpensively. I plan on having 3 of these tables next to each other for a total length of about 18'.

I need to know the thermal conductivity, diffusivity, and emmisivity for stainless steel clad copper. I don't know if thickness matters but this has a thicker copper interior (~.90cm thick) clad with a small amount of stainless steel to equal a total thickness of 1cm (0.01m).

I have the following values for stainless steel:
Thermal Conductivity k = 14.9 W/m * C
Thermal Diffusivity (alpha) = 3.68 x 10^(-6) m^2/s
Emmisivity (epsilon) = 0.58

I have the following values for copper:
Thermal Conductivity k = 401 W/m * C
Thermal Diffusivity (alpha) = 97.1 x 10^(-6) m^2/s
Emmisivity (epsilon) = 0.90


I appreciate your help.

A news story about IEDs in Iraq said all an insurgent needs to do is open or close a circuit to detonate a bomb. My brother says their right; I say that only CLOSING a circuit would do it. Opening a circuit seems ridiculous, you have to close it to send the electricity to detonate something. Who is right?

I've often heard about how you can make a crude flamethrower by holding a lighter in front of an aerosol can and spraying it. I have also heard that the flame can "travel up the stream and into the can", blowing up the can and severely injuring you. I realize that playing with any fire can be dangerous, but I am wondering weather there is any validity to the statements that the flame can travel backwards into the can. Please no anecdotal evidence, I would much prefer some sort of scientific explanation, and possibly a link to some more information.
