How can u drop an egg on concrete without breaking it?

Answer 1

the egg or the concrete? :)

Answer 2

Put the egg in some kind of cradle. The egg isn't supposed to hit the concrete itself and the impact should be spread out over a little bit of time instead of being taken all at once. The cradle should be designed to let the egg rock up and down (damped oscillation) and finally come to rest a few inches above the ground in the cradle.

This can be an application of Newton's Law, which is F = m * (dv/dt). F is the force, m is the mass, and dv/dt is how fast the velocity (v) changes with respect to time (t). Just as an aside, the dv is essentially a notation for delta v (change in velocity), so dv/dt is the change in velocity divided by the change in the time it took for the velocity to change. During the oscillation this will be sometimes negative, sometimes positive, and sometimes zero - but it will never be very very high.

Since the mass of the egg will be insignificant compared to the dv/dt, the thing to concentrate on is to lower dv/dt. Think of a graph of velocity vs time with velocity on the y-axis and time on the x-axis. If the egg isn't cradled, there will be what looks like a step function (shart edge) at the impact. The dv/dt will be essentially infinite (because in that case dt is essentially zero) and the force will also be essentially infinite. If the egg is in a cradle, it never reaches the ground but will come to rest a few inches away from the ground. In the cradle, when the impact occurs, the egg will oscillate around the final resting place (sometimes closer to the ground and sometimes farther away). The damped oscillation around the final resting point is what will spread out the impact and protect the egg.

Now there's just the problem of making sure the cradle is set up for this in all directions or making sure it is guaranteed to hit the ground on one side, etc.

Good luck.

Answer 3

There are some unspecified conditions and assumptions to your question so I will take advantage of a few. We will, however consider that the egg is unprotected.
The height of drop is not specified. So drop it 1/4 inch.
You did not say that the concrete had hardened yet. Drop if 12 inches into the concrete "mud".
You did not say it was in air. Put a piece of hardened concrete under a foot of water.

Answer 4

You will have to package it some way in which you absorb enough speed from the maximum accelleration it will get to a minimum to avoid breakage. Brown eggs are frequently thicker shelled. Check out different materials of foams and concider bungy cords.

Answer 5

Drop it from a height of 1 cm.

Answer 6

Cover the egg in soem sort of material. xo

Answer 7

Put it in between two halves of an orange and wrap tape around the peels.

Answer 8

You should check this wedsite and see how is does work.
