When I was reading this page to understand Archimedes' 'story' I got a question:

According to the example shown, Archimedes found the density of crown by finding the apparent weight. What if he had just measured the volume of water...
Sorry my bad. Yeah the characteristic equation. Once we know it is a second order differential equation, is it no longer needed? Can we describe the whole system with the assumed solution "x = Ce^(λt)"?
Despite of the fact that I am completely out of touch with electrical engineering, I will try to understand as much as I can. Thanks a lot for suggesting me a good analogy.
Thanks BvU. I referred to the "solution" page you recommended where they start solving the differential equation assuming the solution is of the form "x = Ce^(λt)". So if this equation directly gives a simple solution for the position of mass x, the 2nd order differential equation that includes...
The other day when I solved a spring mass damper system in Matlab, I was curious how in olden days would have people solved the equation. We all know the 2nd order differential equation of the system:
However if I know the time, damping coefficient, stiffness and mass, will I be able to find...
Simple questions are sometimes difficult to ask.
I am a mechanical design engineer of automotive gearboxes with a UG qualification and 12 years of experience. My core expertise is into gears and special interest in NVH. In the recent years I see the automotive OEMs cutting down research cost of...
Honestly, I am pretty sure this won't be an interesting taste to the people other than the south part of India [:rolleyes:] Yet I will provide a link:

P.s. - This is not a sweet one. Apologies if you were deceived by the word "cake" :-p
Thank you all! The rice cake turned better than I expected. This forum has now given me an easy and quick method to repeat my traditional food in a new place :)
Like @Lnewqban said, the upper layer of the cake was a bit hard perhaps because of the radiation it received. I plan to cover it with...
Hi... I am really sorry, I don't know the dishes or recipes you are talking about. The way I used to cook these rice cakes is by allowing a continuous steam leakage. Do ovens also have that leakage possibility?
