Thanks mate! I'll look into it

Hi guys, I wanted to ask something that I am interested on Which is on the traditional sewing machine mechanical mechanism (On the foot paddle part) Image taken from Google. From the image above, a typical sewing machine For such application, what is the "Name" for it? Im more likely wanted...

So I'll just have to choose metal from Group 3 to Group 12 ?(Of course with the availability to brought it in market) DOWN a Group: In METALS reactivity INCREASES as you go DOWN a Group because the farther down a Group of metals you go, the easier it is for electrons to be given or taken...

Whoops thanks for correcting :-p

Ya~ Its a battery :-p

There's a confusion before I proceed to the experiment of "Generate electricity out of Salt water" -The variation types of metal that I can choose for replacing "Copper" and "Zinc" from the periodic table. How do I determine which combination will ends up with the maximum efficiency? -How long...

BUMP? I guess...IM right?

Homework Statement Recently I am undergoing such experiment in school and my lecturer asked that, as if any changes in the distance(vertically) will there be changes in the force/reading of it?Assuming there is no changes in anything else except the position of the tools. (Since the "Cell...

Stimulating "Airbags" Recently I'm into it on Airbags and really want to know how it works I've seen some airbags stimulation on YouTube and I'm curious on how to do it? Anyone have experience doing it? Can Solidwork produce such stimulation? PS:Immma Poor English It's Simulation instead of...

Thanks for remind that!

Oh ya! I used to use dy and dx and now i get messed up again!:-p

Thanks Mark for replying I've messed up the thing eventually Based on the related problem dy/dx = -1.3 y Integrate it and apply the boundary condition x(0)=3 \int \frac{dy(x)}{dx}/{y(x)} = \int -1.3 dx log(y(x)) = -1.3x +c y(x) = e^{-1.3x+c} Let C = e^{C1} y(x) =C *...

Homework Statement Given \frac{dx}{dt} = -1.3x x_{1}(t)=e^{-1.3t} x_{2}(t)=4e^{-1.3t} Compute a solution for x(t) if x(0)=3 Homework Equations Superposition Principle and some ODE related Anyhow I refer to this http://www.youtube.com/watch?v=_ECd0Jn7y68The Attempt at a Solution First...

this seems interesting ! so even we're in stationary, we're moving with 8km/s cool! Okay my curiosity solved ! :D
