its a form of simulated rolling so effective time period is about 0.1 seconds and lower
which is similar to the exertion period of jumping on it
yes there is a control i don't do anything to it
but i could get lost in the complexities of soil matrix dynamics under compressive forces and...
Homework Statement
hi I'm trying to design a small experiment based on soil pressure
i've not had much use of some of the equations and principles for a few years so I'm a little rusty
basicly I'm trying to exert pressures onto grass seeds (lolium perenne) in a rough field experiment in...
