Eureka!
As for the second problem, I now get 490.75'. The answer given is 490.83'. I am thinking that is rounding difference. On the first problem, I have no idea why I used cos instead of sine. . . looking at too many problems, I suppose. However, the given answer is 345.43'. After I correct...
Could someone point me in the correct direction? I have no problem working out the angles and lines, but when one has to take into account the perpendicular, then I get confused. It is clear that the relationships are altered, but I am missing something? I have made worked further in the problem...
I posted this question: "Think it will work out?" That question is not this question: "Will it work?"
My reply was not an attempt to be a smartass; if vague. So, feel free not to reply. Under the circumstances, I understand. What do we powerlifters know, anyway? Merely how to lift heavy...
I am unclear as to your meaning.
Your question was put in quotation marks so I supposed you were referencing my own question which was something different, both explicitly and implicitly. My question was framed within the context of my post per se. And it was, put in different words: WILL THIS...
Didn't realize that the raison d'etre was unclear.
The question was: "Think it will work out?" This, taken in conjunction with the prior statement: "My idea is to use it for a fume hood", should erase any doubts as to the tasks which would be the fulfillment of its 'work'. To wit, the removal...
I don't think it matters so much whether or not they are sparkless as long as the motor is outside the flow path... Perhaps the 'bearings' will be an issue, vis-a-vis sparks, uncertain.
Considering some actually use inline motors, maybe it will last a while. I wonder if I could somehow protect...
I just bought this squirrel cage fan off ebay. My idea is to use it for a fume hood. According to seller it runs very well; I will clean, oil, and throw a coat of a paint on it. Got it for 20 bucks. The motor is completely separated from the cage as I wanted. However, it gives no CMF? It is a...
Thanks for the reply. Yes, I was confusing two different concepts.
Is this a more appropriate way to think of the dipole moment:
In HCl the dipole moment refers to the separation of charge within an HCL molecule due to the polarizing effect of the difference in electronegativities of the two...
Yeah, I know... pons asinorum
Polar covalent bonding/dipole moment:
If mu=Qr, where Q is the charge and r is the separation of charges, does it follow that as bond length increases that the dipole moment (mu) would increase in magnitude for the same charge? I do not understand this... If...
Update:
I have located two Mullite tubes; one @ 83.00 and one @ 86.00
Kanthal A-1 Wire @ 15.00-20.00
ITC 100 HT ceramic paste @ 38.00
Kaowool 1" 2600F 2 ft2 @ 13.50

Yup. Using the l=1/4(Lambda), l=3/4(Lambda), l=5/4(Lambda). Considering the system as a node-antinode relationship (which it clearly is), and thus employing .18m as the tine length, viola!
Thanks
Thanks for the reply... The equations are correct in the case of an antinode at each end. I took it that the book's writer must be working it that way, even though the fork has a node at the handle and two antinodes at the ends.
If he is basing it as if it's a node and an antinode then it...
Homework Statement
Name the two lowest resonant frequencies of a tuning fork; each tine is 18 cm long. Speed of wave is 420m/s... ignoring metal thickness.
Homework Equations
F= Velocity/Wavelength; l= wavelength/2, l= wavelength, l= 3/2wavelength, l= 2wavelength, l= 5/2wavelength...
Hmm...
Whether there is current or no current is there a physically extant line that returns to the original source? I thought I was finally clear but after reading the last post, I am not. To not think in terms of a wire that tangibly exists is difficult. I have a grasp of Potential (house)...
