AI Thread Summary
The discussion centers on determining the safe stacking height of plastic bottle crates in public areas, considering potential directional impact forces and wind loads. Concerns are raised about the risk of crates falling and causing injury to pedestrians. The stacking patterns proposed include both horizontal and vertical arrangements, but the exact safety height remains unclear without additional data on factors like mass and surface area. Participants note that solving this issue may require numerical analysis due to its complexity. Overall, establishing a safe stacking height is crucial to prevent accidents in public spaces.

Dear all,

I got a problem to justify the stacking height of bottles crates where locate at the public area.

As you may see the attached photo and draft as reference. The pattern of stacks like 4x10, 4x9, 4x8...(horizontal placement) or 2x10, 2x9, 2x8... (vertical placement).

In the public area, there are lots of directional impact forces and wind load which may make the bottles crates fallen down. If the external force applies to the crates, they will make someone getting hurt when walking on the street.

Assumption:
Plastic crates with empty PET bottles
Wind load (typhoon will not apply to this situation)

The thing is that how many levels should be a safety condition in public area. If you have any question, please feel free to contact me by email)

P.S. I got the additional draft and photo for reference (but files are over sizes putting on this post).

There's no picture. Also, it's not possible to solve this problem without further information (e.g, mass, volume, surface area, etc.). In any case, it is a quite difficult fluid mechanics question which I think would be best solved numerically.
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .
