Will a glass jar full of liquid be less likely to break if dropped than an empty one?
My reasoning is that the liquid is providing a force opposite to the force the ground would if it was dropped.
If you push on a domino from one side it falls over but if there's a slight force in the opposite direction, it won't be as quick to fall.

Why don't you try it and find out?

No, the additional weight increases the energy of the system. Any distributing effect from the liquid would be significantly less than that

Yes. though the difference between an empty and full jar would be almost negligible, since glass has a high compressive strength already.

A good example of this is in the case of soda cans. A closed soda can is very strong, and can support a normal human standing on it. An opened soda can is easily crushed. This is due to the positive pressure from the inside of the can, keeping the aluminum in tension.

I would imagine the same principles apply to a glass jar, but at a smaller scale.

This is of course, assuming it is dropped with the same amount of force applied at collision.

That makes the thought experiment useless. A full jar will always be more heavy than an empty one with the same thickness

what if the jar has flies in it flapping their wings

a jar full of pressurized liquid is VERY difficult to break

This was even better than my example, thanks!

Then let's just say hitting a jar with a steel rod.

Same problem. The empty jar has less inertia

I think it will depend on the properties of the liquid. Denser liquid means more energy to dissipate on impact, then viscosity/density of liquid and liquid/glass interface determines how/whether the glass transfers energy to the liquid at impact.

>> No.10529730

>>10529359
I don't think it would have any effect unless it were at a positive pressure or unless the impact was quick enough that the hydrodynamics come into play. The effect would be small if it were measurable and I still think empty is the better way to go

Drop the full jar from a lower height and an empty one from a higher height, such that they both have the same amount of momentum at impact.

Fucking no....

Glass jars are vacuum sealed, they have inward pressure.

All glass jars are vacuum sealed. Yup.
