A Challenge of a question - May take some time to solve

Opps, the ajar door is 50cm to the left line of the glass.

The velocity of the wind should be able to be tweaked so we can pivet the glass without falling :)

::yawn::

It will need a cat 5 ton blow the building down first

isn´t knots the speed a boat travels at??

47 knots.

138

Do u care to explain how you derived this number :)

Dreamtime calls in my neck of the woods, goodnight

About 730 knts.

The wind force from an F2 tornado should do the trick.

It´s a trick question. A glass does not topple. It tips.

No tricks :)

Where are ur maths nd physics genius´s

Can´t you do your homework yourself?

A Challenge

9810, no, bad enough I had to tell you, now you want me to tell you have to figure it. Hold your breath.

No amount of wind can topple the glass if there is only one opening in the room. Upon entry, wind spreads out into conflicting swirls and edys. As soon as the room is saturated with air, and the higher the velocity of the wind trying to enter the room, the less any air can either escape or enter.

Its only slightly off direct line of site of the open sliding door and is on a brick wall with no obstruction in front of the glass of water, so yes there is an absolute point at which the glass will topple.

All the knowledge of Orbital mechanics, speed of light, gravity, space, electricity and the likes and no one can solve this.

I can assure you this is not my homework, I just thought it would be interesting to see if these claim to be uni grad/professor/physics
types that claim at GLP really are.

You can´t find the answer on the internet.

Practical questions like this would be good in student learnning environments as people could be broken into groups to solve seperate parts of the equation to join at the end for the final answer.

Any how, I am sure one day, some one will come along here, and work the full lenght answer showing their logic in the conclusion.

I actually think that given enough time, I could probably solve it, or at least make a halfway decent effort at it. I got a 97% on my highschool physics final, though that was a couple of years ago :P

I´d need to find out things like the static friction constant between glass/concrete, the effect of the weight of glass + the water on this constant, and the center of gravity of the glass. That´s easy enough, I guess, if I could google the info.

That said, I think the question is flawed like DRSHI says. If there´s only one entrance tó the room, the room would become saturated with air. The kind of initial violent burst needed to filter through the 85cm open glass door to topple the glass in such a large room (and positioned so far away from the door) would probably be strong enough to shatter the entire glass door, thereby changing hte entire equation.

I´m sure the minimum wind force could probably be calculated even with this taken into consideration, but I think they´d have to assume certain things that you haven´t included, like the width of the entire glass door not just the 85cm, the height to the ceiling, etc.

I used to like things like this in physics, but this one is too complicated for me. I´d like to see Idol Harolbed give it a try though :P She seems to know everything about such things...

Did you try solving this yourself?

maybe just buying the material and calculate the effect would be simpler.

Why does one need to find an answer to this?

HEY TEACHER! LEAVE THEM KIDS ALONE!

Nice, now your thinking :)

And you are right, there are a couple more questioned need be asked to resolve the entire equation.

So far you are the only one that has the aptitude to think it through somewhat.

Its not an inteligence (if there is such a thing) test either.

The only I will give is it will not take the door shattering from etreme forces in order for the glass to topple.

LOL @ 1467

A nice solid fart should do the trick.
