The symbol used for engineering strain in most texts is e epsilon. The strain in an axially loaded bar is defined as: If a cut is taken perpendicular to the bar's axis, exposing an internal cross-section of area A, the force per unit area on the face of this cut is termed STRESS.
There are few memories we always cherish, no matter Pillar strength equation old we grow with them but they remain close to your heart because it is about someone with whom we are close and dear with — Our Sibling. Being the eldest one among the two of us — Brothers, our relation is somewhat like one where both of us look at each other and ensure the other is always away from any kind of problem.
Of course, it matters that we exchange the pleasantries, talk to each other and wish on the important days but actually, both of us expect and to matter is to stand for each other whenever the either of us is in need.
Though it was just about regular colony cricket, there was a lot of planning that went in for that, and we would be regularly scolded for putting Pillar strength equation marks on the walls by throwing back and forth on it.
That is a good strong memory of growing up, I remember how my little brother would take the bat away if he was not convinced that he was out, sounds funny when I recollect now. That was then and there, but as we grew up, we chose our paths where we wanted to see ourselves placed in life and today, fortunately, we both of us have realized our dream.
I know my brother is guided more by the emotions, and his passion for writing took him past the regular crowd of engineering and placed him there.
That was some time of our lives when in the final year of his engineering, he dropped me a message stating how badly he wanted to be something else. Somehow, everyone in the family took it well, and I loved how brilliantly my brother in no time pushed himself and carved a niche for himself in the world of journalism.
Every time I think about it, I feel proud of him.
I try taking lead to be there for him, my overprotection does get irritating for him at times. And like I always wish for and say, no matter what I do, I want him to watch him achieving the best of everything in the world and make it bigger than all of us.
There is a marginal difference of two years and 3 months but we have a respect for each other. When I see other kids fighting, cribbing or blaming each other, I too wish to get into such situation with my bro…but we never indulged.
We are different, we hardly exchanged bitter words.
Being elder, I succumbed to his childish demands and never ever complained. Once or twice, I spanked him but he never retaliated or get into action…he cried and that was enough to tear my heart out…and say sorry.
We are different in many terms but still, an unseen force attracts us and we are indeed the pillar of strength for each other. He fills my shortcomings and I conceal his and we work together on our strength. When I feel low or defeated, I look for his assurance that all will be well.
On the emotional front, I am emotional and his lookout is quite practical. He guides me on these moments where I feel stuck. May this compatibility and partner in crime remains the same throughout life. I love him and wish to have him as my sibling in my next life.Request PDF on ResearchGate | New pillar strength formula for South African coal | The data base of failed pillar cases as used by Salamon and Munro () in their original analysis to determine.

Last Name. Beam Bearing on Concrete. Last Revised: In this case P p is the nominal bearing strength of the concrete surface is computed using SCM equations J and J In actuality, equation J is a special case of equation J (when A 1 = A 2), so equation J can be used at all times.
The presence of shear stresses in pillars and the effect on factor of safety  wwhere K represents the pillar strength constant (downgraded uniaxial compressive value), w the width of the pillar, and h the height at which the mining is taking place.
Yield strength, proof strength, ultimate tensile strength, critical load for instability (buckling) can be selected for failure stress but this selection depends design, material in use and type of .
equation, pillar stability curves can be generated. The pillar stability curves generated using this procedure do not resemble the empirïcd curves derived by other authors. Further Figure 1: Strength factor contours of a pillar using ni = , s = and oc =
