RE: Salt Lateral Bin Pressures

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Wait, I just had a thought!
Go get a LARGE box of granulated salt--or many boxes. It's cheap, make your client pay for it.
Then, go into your garage. Put a tarp down. Dump ALL that salt in a HUGE pile (Do it so that it'd doesn't get "smushed" but piles up real nice and natural-like). Then get out your trusty angle-measuring device, and MEASURE the angle of repose, which (IIRC) equals the angle of internal friction!
Now THAT'S engineering! Ben Franklin would be SO proud!

Subject: Salt Lateral Bin Pressures

I am working on a salt storage building.  Anyone have a good reference for the lateral pressure exerted on a bin by a heaped mass of salt?
