How to calculate the bonding force due to wringing effect in slip guages

AI Thread Summary
The bonding force between slip gauges is influenced by factors such as surface finish, material properties, and the wringing effect, but no direct relationship exists among these variables. The complexity of the bonding forces, including molecular attractions and surface tension from contaminants like oil and water vapor, complicates theoretical calculations. Accurate assessment of these forces requires advanced calculations that consider chemical bonding and atomic structure. The discussion emphasizes that theoretical calculations for bonding forces in slip gauges are not feasible. Understanding these interactions is critical for applications in civil and mechanical engineering.

Bonding force between two slip guages will be inflenced by surface finish,material,wrining effect etc., what is the relationship between all ? Anyone knows how to calculate theoretically?

Its a very difficult question I must say. There is no direct relation between the terms you mentioned. This question seems to be more engineering based also. Moreover , its more of civil or mechanical engineering. There are many bonding forces like molecular attractions which can cause adherence in these gauges even without using lubricants. Also there is surface tension acting from oil and water vapour. Apart from them , there are other minor forces. So there is no direct relation between the terms !
We CANNOT calculate them theoretically. It'll (for instance resistive forces due to wringing) require a higher level calculation from chemical bonding to atomic structure.

Moreover this might also help :

I think it's easist first to watch a short vidio clip I find these videos very relaxing to watch .. I got to thinking is this being done in the most efficient way? The sand has to be suspended in the water to move it to the outlet ... The faster the water , the more turbulance and the sand stays suspended, so it seems to me the rule of thumb is the hose be aimed towards the outlet at all times .. Many times the workers hit the sand directly which will greatly reduce the water...
