AI Thread Summary
The projector in a cinema theater can be positioned in various locations, including the top left corner, center, or top right corner of the wall. However, the optimal position depends on the alignment with the screen and viewer seating. Adjustments can be made if the projector's lens system allows for offset positioning while maintaining parallel alignment with the film and screen. Techniques similar to those used in large format cameras can help correct for perspective issues. Proper placement is crucial for achieving the best viewing experience.

TL;DR Summary
Projector location in Cinema Theater.
The projector location in Cinema Theater can be positioned in Top left corner, Center, Top Right corner etc?

I mean Can the projector location in a Cinema Theater can be anywhere at the top of the wall?

Sorry, I have no idea what you are asking. There is obviously an optimum position for the projector in a movie theater with respect to the screen position and the positions of the movie viewer seats.

Can you please post more details for your question and maybe some sketches to explain the positions you are asking about?

The projector can be anywhere if the geometry of the lens system can be offset sideways, while still remaining parallel with both the film and the screen.

Large format cameras sometimes support the same technique to correct for perspective. https://en.wikipedia.org/wiki/Scheimpflug_principle

Thread 'Question about pressure of a liquid'
I am looking at pressure in liquids and I am testing my idea. The vertical tube is 100m, the contraption is filled with water. The vertical tube is very thin(maybe 1mm^2 cross section). The area of the base is ~100m^2. Will he top half be launched in the air if suddenly it cracked?- assuming its light enough. I want to test my idea that if I had a thin long ruber tube that I lifted up, then the pressure at "red lines" will be high and that the $force = pressure * area$ would be massive...
I feel it should be solvable we just need to find a perfect pattern, and there will be a general pattern since the forces acting are based on a single function, so..... you can't actually say it is unsolvable right? Cause imaging 3 bodies actually existed somwhere in this universe then nature isn't gonna wait till we predict it! And yea I have checked in many places that tiny changes cause large changes so it becomes chaos........ but still I just can't accept that it is impossible to solve...
