Re: Active Pressure Coefficient of...

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Although I'm sure the material in question is quite "active", due to the "activity" involved in the composting process, the at rest pressures or fluid pressures similar to the unit weight of the material would probably be more nearly what you would see on an unrestrained wall.  Picture gas bubbles causing expansion and readjustment of the material as they form and dissipate.

As you actually working and need some sort of answer or another one 
of your little jokes?

Well, I'm hurt. Why ever would you suspect I'm being anything other than
intensely serious?

(The chickens that got squished by the wall that failed under this load
certainly didn't think it was funny).
