Interesting point.
If a beam has been plasticly deformed at some stage in its life and then bent back and unloaded...
Will elastic bending theory of the likes of f= my/I still work the next time it is loaded in what was its elastic range of load?
Thanks very much for the depth of your reply. It has helped me a lot in terms of my investigation and the right questions to dwell upon.
Actually I am fairly close, I am about 8% out with one method - strain = my/EI where EI was calculated by measuring the deflection and from that obtaining...
thanks for the reply. Thats interesting, though I probably should have thought it would be along those lines.
What factors then do you think would cause it to have a different strain reading than theoretically calculated results useing bending theory?
Besides stress raisers and innacurate...
How does one work just out of interest?
I use it when loading a steel beam to see the strain induced in the web of a chanel section.
can't figure out how it would work
Right, well I've figured it out.
So for those of you who care... its actually an extremely simple connection... the hours I spent completely unwarranted.
I in bending theory you find that
Curvature, or, 1/r = M/EI
where r is the radiius of curvature and M is the moment.
The slope...
Hi, I was really hoping someone could help me...
I have a beam, simply supported and I place 2 point loads on it (equidistant from either end). I measure a range of deflections (of the beam) using gauges as I increase the loads (always having the same load at each point). I measure these...
Gday,
This is a very simple question and it should only take one sentence to answer. It's not worthy of these forums, lol, but despite my efforts I cannot find an answer through google.
If a light fitting says '40 watt max' and I stick a 60 watt bulb in it, will that have any adverse...
yeah I can see why that would happen if you positioned the camera at the WHOLE television ie the frame and the screen.
But what if you positioned the camera at ONLY the screen...
This is probably painfully simple, and is not a 'brain teaser' as such but this seemed like the most suitable forum.
My bro and I were having a discussion tonight and we stumbled across a problem that probably lead to more discussion than it is worth, but since we still can't come up with a...
I was reading something today about it being stupid to own a radar detector in Australia because the police carry radar detector detectors with them. Is this even possible?
I would have assumed that radar detectors don't send out a signal of sorts but only attempt to detect incoming radar...
Perhaps. I suppose there are many factors to consider. I don know that at the Uni I studied at though, the Japanese students were advised to pretend they were Korean to avoid possible troubles in the country.
I studied.. wait for it... at Nanjing University. So I suppose I was in an extreme...
Oh I see what you are getting at Bobg. My piston idea involved pistons entirely separate from the tanks, not turning the tank into a massive piston. I might find it difficult to get an airtight disc to fit the tank itself perfectly. But I like the idea. I've got a mate of mine calculating the...
