I found a Parallel Computing Toolbox. I'll get back to you if I face a problem. Thanks!

My OS is Windows 7 64-bit. Can you enlighten me a bit over the "distributed computing toolbox"? Thanks :)

I wrote a program on Matlab that is supposed to solve a 2-dimensional dirichlet boundary condition heat transfer problem. In programming context, it uses a number of iterations in series to calculate the next value using data acquired from the previous iterations. I am running MATLAB...

I wanted some help in finding out the time taken for a differential mass of gasoline being burnt in the cylinder during the power stroke. Also, does it depend on the residual temperature of the mixture? I tried to find it out through Arrhenius equations but am having a problem finding out...

Thanks for the replies, :smile: Thats quite a wide range of temperatures. :-p I wanted to run some theoretical stress analysis on the piston head for the power stroke. I'm having a hard time figuring out an effective approach to calculate the pressure variation...

I wanted to know what exhaust temperature range would i get with a 48cc 4 stroke single cylinder gasoline engine operating at standard parameters. Also, what variation in engine efficiency would i get by varying exhaust temperatures using water as a coolant?

uh oh... this was one of those times when u assume that the listener ( or reader in this case ) knows what u r thinking... :redface: I forgot to mention... the force is equally distributed throughout the plate surface... What would happen for this case?

If i were to attach 2 helical springs (of same uncompressed length but different Spring constants) to metal plates on both ends and then apply a compressive stress on one of the plates, will both the springs compress the same? even though they hold a different tendency for compression...

I need to devise a way to measure the torque of a Rotating Motor. Now i already have 2 ways in mind but both of them require that the motor [SIZE="4"]stops while still being powered by a battery or something. ( I think we risk permanent damage to the motor ) Can someone point me to a...

Sorry... Didnt really think about it!:biggrin: You got it Tim.:approve:

You got the first derivative completely wrong. Derivative of Tan x is not sec x, its sec^2 x. This way your problem goes as follows. y = x tan x y' = tanx + x sec^2 x and y" = sec2x + x ( 2 sec2x tan x ) + sec2 x [ Derivative sec2x is given by first reducing the SQUARE FORM to a...

thanks for the info. Do you have any tires in mind that would do good? I need to get the exact tire rolling drag co-efficient. Please point me to a link on the web that would serve my purpose. Thanks again!

Ok here goes, I am planning to build a car worthy enough of participating in the Shell Eco marathon 2011. Now i have the design and power needs sorted out at the moment but there is still a lot i have to do here. Here is the basic goal that me and my team are working on. "To build a car...

its a small car actually... a single driver would hardly fit in. Its about 2 meters in length and 110 cm high. What i need to do is increase its efficiency to as high as possible. Would bicycle tires do good? Anything else that i need to be taking into consideration? Thanks for the help.

I know its a pretty noob question... but still, What in the world is Entropy? Can't seem to grasp its idea.
