 Jan 30 revised Calculation of the maximum load to the bar edited tags Jan 30 asked Calculation of the maximum load to the bar Jan 18 asked Clouds in closed hydrosphere Nov 12 comment Ping-pong ball pontoon Sure - the "most precise" method will be experimentally test it in real... :) :) Nov 12 comment Ping-pong ball pontoon just found this 124.42.15.59/ck/2011-05/165/053/860/957/… - i hope it will help me getting the answer ;) Nov 12 comment Ping-pong ball pontoon Hm.. so.. probably the question is how much force can withstand the ball by contact-point forces... Is here a difference when the balls will be aligned in row (like vertical "oooooo" - 2 contact points only)? Any idea how to (approx) calculate the crushing force? Nov 12 revised Ping-pong ball pontoon poping -> crunching Nov 12 comment Ping-pong ball pontoon Not a homework, just thinking about variable buoyancy pontoon what will have a constant height above water level depending on weight. And are your'e sure about the topmost row? Because at some depth the balls must withstand the pressure of the water PLUS the pressure (forces) what are transferred via the contact points...

I asked about the "soil" because i not want asking about the engeneering (buildings), but making a hill from "natural materials" like soils, sand, rocks and so on... Jul 29 awarded Student Jul 29 comment How to calculate the highest theoretical artificial hill? @dmckee - yes, becase it is importatnt for "setting" the base of the hill height. From the above link, the highest possible hill is 49km high, but the question is - where is its "base"? (it is not the sea level). Jul 29 comment How to calculate the highest theoretical artificial hill? Yesss! The link is exactly for what I'm looking. Thanx. ;) (Only don't understand the 4.9km result - because in the earth Everest is 8+Km - but will study the article more deeply.. (4.9x10**4m is 49km) Jul 29 awarded Supporter Jul 29 awarded Scholar Jul 29 accepted How to calculate the highest theoretical artificial hill?
