hi ravisbassi, I'll give you my thoughts on it and I hope I am not discouraging anyone from writing a phd about it :mail1:
The mechanics of the egg breaking that you mention is dependent on the following main factors:
1. The geometry of the egg shells
2. The mass of the eggs
3. The force that you apply to each one of them
4. The respective crash spot on each egg
5. The material composition & density of the shells
If you want to make sure that both your eggs will be broken at the same time, make sure that the 5 factors above are the same in both eggs. Unfortunately that cannot happen because:
1. There are not two eggs with the identical geometry (i.e. 100% identical)
2. There are no two eggs with the identical mass (i.e. 100% identical mass, in every atom)
3. The force that you apply is different, your arms don't have the same strength and also they are controlled by two different brain hemispheres, this makes them have different degrees of control, speed, force etc.
4. Suppose you can fix somehow 1, 2 & 3. Still you have to make sure that you hit them in the respective spot (i.e. not head with bottom, head with middle and so on), you need some damn expensive lasers to calibrate the hit spots :wacko2:
5. Last but not least, the material composition and density can't be the same, ever, not even from the same chicken. :dash2:
However, if we make use of some physics we can see that:
m1 x V1^2 /2 (Kinetic Energy of egg 1) + m2 x V2^2 /2 (Kinetic Energy of egg 2) = Energy is transformed to heat + energy that is used to deform shells + energy that is used to break shell(s) + Kinetic energy of the broken shell pieces and egg fluid that escape their initial position within the egg.
Most of the energy I guess goes for breaking the shell and as kinetic energy of the broken shell pieces and egg fluid that escape. So if you want to maximize the probability of breaking both eggs upon impact, I suggest you do the following:
1. Choose two eggs that appear to you as having the same geometry and mass (this can take some time and money, but if you want to get an answer ..... )
2. Tape the eggs with duct tape, several times, just leave out the hit spot and a small area around it, for example the top. (the taping will act as reinforcing for the shell, and even when it will break, the pieces will not fly around and the fluid neither, so you remove the kinetic energy of the pieces from the equation and hopefully that extra energy will be enough to break the shell of the other egg)
3. Extend your arms 180 degrees apart and make them meet with the highest speed. Do this movement in a certain plane, use a desk or flat surface to guide you. Try with some tennis balls before you try with the eggs).
Enjoy!
