Ok, let me refrase my question a bit.
Can somebody tell me how the rod goes about to "sway" when a impulse is applied on the bigger block with mass M?
If you know a book or a homepage, which you could refer me to for this problem, I would apperciate that as well.
Do you really mean 700 W as in power?
Because then you would have to many unknowns, like the current for instead.
If you mean 700 \ohm, as in resistance, then it is not to hard to calculate the answer.
Well, I have come up with the problem myself.
What I am trying to get is an equation for the motion of the rod, or cantilever if you will. My problem is that I am not sure how to relate the force influencing the heavy block the rod is attached to, to the rod.
I think I need to make a...
Hi!
I want to calculate the movement of the rod in the picture, but I don't know how to put up the Lagrangian for the problem.
I have the Shear modulus, \mu, for the material and M>>m and \theta = 0. I need the Lagrangian and from there on I think I can manage with the calculations myself...
Sorry for the late reply, no internet connection during weekend.
Well my purpose is to try to calculate when dos the wire melt at different currents.
Do you mean using resistivity to calculate the voltage current relation or is there other information I should look for in the gage tables?
Hey,
I am currently trying to calculate how much current a "wire" of very small dimensions can take. This "wire" is of dimensions of 100 micrometer and radius of about 1 micrometer.
I have tried to use the Stefan-Boltzmann law or use the specific heat capacity, but in there I do not include...
